I just think it's time. Plus, with college now more like the NFL than ever, I'm not sure that his message is still getting through (same reason-$). It didn't seem to last year, and I think that was more of a new normal than an anomaly. I think players will all give lip service to "the process," but as they make more and more $ in college, I believe we'll continue to see players making mistakes that either never happened before, or never happened with the frequency that we're now seeing. We just had the most penalized Alabama team under Saban, I believe.
I also think a coach hanging on too long can do much more damage to a program than one leaving a year too early. Belichick used to be the best at this when it came to players, but now, not so much.
I doubt anyone else on the board, or in, and I hate this term, "Bama nation" agrees, and that's fine. But I'm ready for a change, for those reasons and a few more.
