There is a really good article on another site that supports what I've said time after time on this site about attrition. Iowa has had the most of it in the big ten in the last 5 yrs. (I believe avg. 7-8 yr.). Iowa is never going to get a lot of 4 and 5 star recruits no matter who the coach is. Get over it folks. If you think an Urban Meyer would even come to this small market corn state, let alone bring in a bunch of 4-5* recruits, you're higher than a Coloradian smoking on Pikes Peak

But KF is one of the best at developing kids and he still is. The statistics don't lie. You just have to stay in the program for 4-5 yrs. I don't know the percentage (but it's pretty high), but the kids that do stay (and don't get hurt) end up drafted or at least get a look as undrafted free agents. If kids have to hit the field before they are prepared (like some LB's last year) they are going to take some lumps (like Hitchens, Morris, and Kirksey did their soph. yr and look how they turned out) It's just the way it is. So the key is to figure out this attrition issue and stop the bleeding. If everyone stays and a couple young DE's step, Iowa's D is going to be stellar in 2016 (they will be much improved this year). Mark it boys!
As far as coaching, chemistry is huge just like with a basketball team. I stated in jan. that the coaches didn't seam to be on the same page and then one of the Iowa assistants came out and said pretty much the same thing. NP was special, but PP is a great disciple of his, he just needs to get everyone together (I don't think Woods was seeing eye to eye with Reid, thus the move to TE's). Same way with the offense, the coaches were not on the same page with the scheme, which is why BF is coordinating the run game now. If him and GD don't get it together, it won't improve. KO ran a boring offense (according to most here) but he at least seemed to be able to call up the right play at the right time quite a lot. I haven't seen that at all out of GD. Although this staff still knows how to develop talent, I agree with some that the in-game coaching better improve. Plus, special teams have to improve markedly. There are so many tangibles, and when your not one of the big boys, there is such little room for error in any area. I think what KF is really focusing on this year is cleaning up all the little things.
Sorry, so long, but you asked
