Lets break it down a bit differently. Lets compare positions, i.e. QB to QB. I am sure at the end of this I will be accused of seeing things from Hawk Colored glasses so feel free do disagree with me, but please post a reason.
QB Edge Iowa- JVB comes into the season having played significant roles in three games of the 2009 season and only saw one drive in which a game was being contested last season- opening game versus Eastern Illinois. Has been in the program for 3 seasons and is the clear cut starter. Career record as a starter 1-1 (also played most of the Northwestern game leading Iowa to 0 points in 2009). 200 yards games passing- 1, TD/INT 3/5
Tiller is fighting JC QB Jantz for the job, heads into fall camp on the 1 line. Has more experience than JVB, has a career record of 1-4 as a starter (also played a significant role in win over UNI in 2010), but the one win was at Nebraska. More of a runner than a pure passer has rushed for positive yards in each season and has 2 rushing TDs (both in 2009). 200 yard passing games- 0, TD/INT 2/4
Jantz is a minor legend because of his name. Competed for the starting job this spring and has a chance to win the job in the fall.
TB Edge Iowa- Marcus Coker makes this a no- brainer. However Iowa has very questionable depth behind him and may struggle in the running game if her were to go down with injury. It is also a bit of an unknown how well he catches passes and Adam Robinson will be missed as much for his rushing as his pass catching (24 291 yards 1 TD). Iowa has a chance to have a very good line and the screen pass was a bit underutilized last season. If Coker can catch he could be devastating in screen situations. Backed up by De'Andre Johnson, Jason White, and a host of freshman.
This isn't as big as an edge as Iowa fans may believe- Shontrelle Johnson who has very good speed and is a bit shifty. Johnson will likely receive the most snaps at this position but ISU has at least two others competing for time in S.E. Polk native Jeff Woody and James White. Alexander Robinson is leaving big shoes to fill, however and was a solid contributor in all phases of the game.
WR Edge Iowa- McNutt and Keenan Davis again give Iowa an edge in this spot. McNutt is coming off an 8 TD (2 more than ISU's entire returning pass catchers from last season) season and could improve on that this season as DJK is gone. Davis has big shoes to fill but seemed to flash several times last season and already has as many TDs in his career against ISU in limited reps as any ISU receiver possesses against Iowa. After these two Iowa is a complete unknown. Iowa will be missing DJK, Sandeman and even Chaney. A lot of unknowns here, Iowa has at least 5 bodies competing for time behind Davis ans McNutt.
ISU is looking to replace the steady Jake Williams and the enigmatic Sedrick Johnson. They currently possess three receivers who have received time and been a bit productive. However those three combined for less yards than McNutt gathered last season (861 for McNutt to 808 for the ISU trio) and they had only 1 more yard than McNutt last season in the game on 4 more catches.
TE- this is a huge edge for Iowa. Iowa returns Brad Herman who was dominating as a blocker and before last season was thought of more of a receiving tight end. Herman has excellent size, speed and athleticism for the position and will possibly have a hard time holding off the freakish C.J. Fiedorowicz. Iowa is deep at this spot with Zach Derby capable as a 3rd stringer and three freshman on the way.
ISU is losing a very talented player in Collin Franklin who led the team in receptions and yards and they look to have nothing special at this position. This may not matter much offensively to ISU as they can line up without a TE, but this is certainly the biggest positional gap between the two schools.
Offensive Line- again this is closer than many Iowa fans realize. Iowa returns 5 players with starts last season and has two promising youngsters waiting for an opportunity in Boffeli and Scherff. This line will likely feature two NFL draft picks for next season in tackles Rieff and Zusevics and Ferentz looks to be on track for an NFL future.
ISU returns Osemele who is very highly thought of by NFL scouts and such, and Burris and Hicks who possesses very good size. Burris was spotty at times and really struggled against K-State last season. ISU will be replacing their best lineman from last season and another 2 year starter. I have no idea who the replacements will be but they won't be better than Lamaak.
Defensive line- push Iowa returns Binns and Daniels who had 11 TFLs last season playing part time. Binns really struggled and the highlight of his season was his 20 INT return for a TD. Iowa must have Binns bounce back. The rest of the line is likely a mystery but Iowa has several players with high potential including Daniel, Alvis, Hardy, Davis, Nardo, Forgy, Bigach and incoming freshman Darian Cooper to fight for the two open spots. Iowa likely has the deeper unit overall but you generally only play 4 at a time.
ISU loses only two players from last season and returns Lattimer who made honorable mention Big 12 last season in limited reps and a bunch of small guys at DE that are super fast and pass rush specialists like Maggitt, Neal, and Nelson. They have combined for 1 sack last season ( I know Nelson red-shirted). ISU also returns their best defensive lineman Rump. I already spelled his whole name in the OP and thats enough. I personally though Rump was a standout last season for the whole season and could give Iowa trouble in the next match up. ISU also returns McDonough who looked solid at times last season. They also have an impact DT coming in named Pompey who has to be called THE VOLCANO please. He is listed at less than 260 on ESPN.
Linebackers- push. Iowa returns three players with quality reps- Nielsen, Morris and DiBona. DiBona was limited in the spring with Rhabdo and another injury (shoulder?) Nielsen was on track to out produce A.J. Edds at the Leo position and looked incredibly solid in both phases. He had an interception versus the Clones and 9 BU/PD last season in 8 games. Morris can be penciled in as the Mike for his next three seasons and did a very good job versus the run and will likely be bigger this season. He had 70 tackles in only 7 games of starter reps. He also looks to be Iowa's best blitz linebacker in several seasons. Iowa has very little proven depth and there will likely be a huge battle for the Will spot.
ISU has a solid tandem as well in Knott and Klein and they should be even more effective with the expected improvement from ISU's d-line. ISU played a lot of 4-2-5 last season and has no proven depth or a sure bet at the Mike position. however Knott and Klein have proven to be solid playmakers in both phases.
DB- push Iowa returns Prater and Hyde- who may be playing free safety instead of corner this season. Iowa also returns Bernstine, Lowery, Castillo, Miller, Nielsen and Swanson. Iowa also has a few freshman that avoid the red shirt this season. Iowa loses 7 years in starting experience in Sash and Greenwood and they had 6 INTs in the last 2 meetings.
ISU returns 3 players with a lot of reps last season- Benton, Johnson and Reeves. Reeves is only 5'7 and that will be tough on him against Iowa as McNutt is 6'4 and Davis is 6'3. Benton is solid at both CB and Safety but if ISU is going to play 5 DBs every down they have virtually no experienced players left and are losing an underrated O'Connell and the sticky fingered David Sims (6 INTs in his career). ISU struggled mightily versus crossing patterns and play action last season as Stanzi averaged 18.5 yards on 11 completions.
K edge Iowa- Meyer will likely be the PK for the Hawks and is coming off an excellent freshman year going 14-17 (2-3 from 40-49) and showed a big leg on kick offs with 15 TBs. However as he won the regular kicking job his kick offs dropped a bit. Iowa also struggled with kick coverage and will likely be very young, especially early on the Kick team. Trent Mossbrucker is also an option here.
ISU's Mahoney has seen a steady decline in his accuracy but has a big leg- career long 57 yards and had 16 TBs last season on 52 kicks and helped ISU to a solid 41.7 net.
P Huge edge for ISU- the VanDerKamp was excellent last season. ISU's return team was not spectacular.
Iowa has no clear cut punter and this battle could rage into the season. Iowa is replacing one of the best punters in the nation and a likely NFL player in Donahue. Iowa's punt team was not very good last season including a punt block versus Arizona and turning several solid punts in to TBs last season.
Return- Edge ISU. ISU returns all their key returners and all three are talented.
Iowa returns Kennan Davis at KR and he has not shown the kind of big play ability at this position to keep his role. Hyde at PR seems to have potential and may actually come to fruition.
Summary 5 Edges for Iowa on offense, 3 pushes for each team on defense, 1 edge for Iowa in special teams and 2 edges for ISU on special teams. Weird things happen to Iowa in Jack Trice and this will be the best defensive unit for ISU in several seasons but Iowa should and will be favored in this game.
