Agreed. I also think they are going to be kind of weak at QB. Tiller still looks to be the main guy and he was less than stunning whenever he was under center the last two years. If Jantz or one of the younger guys doesn't step up and Tiller remains the QB I think ISU is going to have a lot of problems putting points on the board.
One issue for the Cyclones is that their interior line has some potential in '10. I really like McDonough. Also, Rumpolhamer (they call him "Dutch") is a pretty tough guy to move ... and plays with great leverage. Lastly, they've added what seems to be some quality depth in Pompey (plenty of beef and athleticism) and a big JUCO transfer too.
Lattimer is arguably the best DE that they have against the run. The JUCO DE, Nelson, who had to sit out a season due to grade-issues sounds like he could be a pretty explosive player for them ... however, when coaches say that, it usually implies that the guy can be good rushing the passer ... but that is often at the cost of overpursuit ... that hurts against the run.
While I won't go as far as Mesaclone when it comes to talking up their LBs ... I will admit that the 'Clone LBs are darn good. Definitely high quality players with plenty of talent.
Also, the 'Clones have a solid group of DBs too. However, not unlike Iowa, they were forced to move one of their CBs over to safety (Benton). Thus, I'm not certain how consistent the ISU safety play will be early in the season.
I think that the Cyclone starting D looks pretty darn solid on paper ... however, the bigger problem with their D regards overall depth and experience. They don't have a whole lot (of experienced depth) at a number of important spots (safety and LB, in particular). And that lack of depth could hurt them.
Furthermore, as you rightly point out, it's not at all clear to me how good the Clone O will be.
