I was originally in the corner that guys at low D1 and mid majors were just overlooking some very good players and I still think 5 or 6 months ago that was definitely the case as we were constantly seeing D2 guys getting drafted that could've excelled at a mid major. Here is a guy I signed to my WVU team a few months back
http://whatifsports.com/hd/PlayerProfile/Ratings.aspx?tid=0&pid=1778995. I signed him for $110 and that's the most I could've spent on him and he was even available to my D2 school in the same world so any D1 could've had him fairly easily.
However I'm seeing more and more that guys like this aren't around anymore (ranked in the 100s but still good). I came to the realization that recruit generation needed to change when looking at D1 conference RPI in Tark and last season in Knight, the BCS conferences are just head and shoulders above everybody else. In these worlds every BCS conference is or was over .5750 RPI while every non BCS conference was under .5000 are just above it. I've never seen the gap so big. I know it's partly due to the lower levels of D1 being empteir than in the past but it's likely emptier because it's harder to get quality recruits.
