Why would any WR, QB, or OL recruits ever want to play for Leach. It's not like his teams continually break offensive records for yards, TDs, score, etc. That's the kind of stuff offensive recruits like.
Oh, wait....
well here is your first problem. As far as college players go we aren't hurting in 2/3 areas you listed. Yes QB is an issue that can't be over stated. But Leach hasn't produced an NFL qb either. He has 1 good WR and I honestly don't know of any OL players at the next level.
here is the underlying problem. Yes recruiting is a massive issue. Winning will go a lot to solve that. The biggest issue this year, last year and tomorrow is defense. So how does hiring an offensive minded coach fix that? Leach has no track record of success on the defensive side of the ball that I recall.
players drafted under mike leach. 2 QB's and a bunch of OL.
