Commitments do seem to be coming earlier. I don't know if that's fact or perception, but it's my impression too.
A couple years ago, I was talking to Adam about CU recruiting and the best strategy for the Buffs to use. At the time, he was partial to the approach that Boise State used to build its program (and Hawkins tried to bring here -- successfully, at first). Basically, that the prospect ratings this time of year by the premium sites and college coaching staffs are based on junior year performance, that young men develop at different rates, that some guys are injured or sit out due to transfer rules or are stuck behind a big time senior during their junior seasons, and that if you wait for those guys who blow up as seniors or the guys who get caught in the recruiting wash because spots filled or they were cut loose by their top schools... there is a better opportunity with lessened competition to find better players late while also making fewer mistakes. With Hawkins, as we know, it blew up on him when he waited and then recruited as a lame duck late in the process & then we had a transition year with nothing done at the time Embree took over. But this approach, assuming program stability, seems to be a better way to build. (fwiw, it will also result in a lower rated class that is more talented than it appears to be.)
