Colleges do focus on packing stadiums. However, they've generally not had an interest, per se, in developing NFL ready QB's. They want to develop quarterbacks that can win games for them, whether they'll be NFL ready or not. Schools like Texas Tech and Navy have developed numerous quarterbacks that put up incredible numbers and led winning collegiate teams. None of their quarterbacks, with the exception of Roger Staubach, have done anything in the NFL. Of course there are some college coaches that do want teams that win games running NFL-type systems. They'll develop NFL ready quarterbacks as a result. The primary goal, however, may be to enhance their coaching resumes to show their strengths are what the NFL will be looking for. Regarding a developmental league, it already exists at the collegiate level. But why pay players? They already get a free ride worth tens of thousands of dollars, free coaching, lots of publicity, and as a bonus, some of them may even learn something.
