Well I think if you look at roughly the same time period I think Iowa's record lines up pretty closely with what the draft numbers indicate. I could be wrong on that though. Iowa has had a lot of good players over the last decade.
Impressive numbers of OL, TE and DB's (mostly safeties). What jumps out is the lack of skill position players (RB, WR, QB), which reinforces what we've known. Iowa has done a very good job of developing talent where development arguably makes the most impact (OL, TE, DL, safety) but it's very difficult to "develop" your way to a NFL-caliber RB, QB or WR.
