here are some some quick and dirty rankings for the Big Ten units we face including Iowa.
9: Minnesota- lost two wide outs although they do return McKnight. TE Eric Lair is a solid pass catcher but unless Gray moves back to WR they are likely the least talented and unproven group Iowa will face.
8: Nebraska- again return leading receiver and a TE who is talented- rest of the depth chart is completely unknown.
7: Iowa- has talent but mostly unproven- McNutt is a given and deserves his ranking in Jon's article. K. Davis, Herman and CJFed will have to step up to replace 109/1,432/14 Tds. That also doesn't include Adam Robinson's receiving stats.
6: Indiana- return two talented receivers in Belcher and Wilson but lost 130/1387/10 from last season's receiving corps. A proven Td producer and solid TE returns in Ted Bolger along with steady Max Dedmond
5: Purdue- Keith Smith and Justin Siller will join the aforementioned Edison for the Boilermakers. the also return leading pass catcher in TE Adams. Cortez Smith is the only real loss to this unit.
4: PSU- a lot of talent at this position. I am ranking them #4 because several key players are injury prone and they have the weakest QB(s) of the remaining top four teams. Replacing Brackett and Zug- quality third down and gritty players but replacements are more physically talented.
3: Michigan- a lot of bodies for a team that really spread the ball around. No significant losses at this position and legitimately 5 deep headlined by Roundtree and Stonum
2: Northwestern- Physically this may not be the most talented group, but they are very effective. Rashard Lawrence is one of the most physically gifted NW players I have ever seen. Replacing Fields and Stewart who combined for 65/745/2, but return primary targets Ebert and Dunsmore.
1: Michigan State- two key losses (so far, its a long off season in East Lansing), return Cunningham, Martin and Nichol, who adapted very well from QB to WR. Depth at both WR an TE if the TEs can stay out of trouble. Lost Dell and Gannt who combined for 75/1089/9. Martin may be the best player of the bunch and will likely step into Dells role as leading receiver.
I haven't looked at Wisconsin, Illinois or OSU because if we play them this season we will know as much as we need to.
