A couple of years ago, rumors were circulating that were both unsubstantiated and salacious. So they're not allowed on TideFans. But they did center on favoritism even though the favored player(s) didn't produce much on the field. It's one thing to show a bit of favoritism toward Bailey Hemphill or Montana Fouts. It's quite another to show favoritism toward a down-the-line player.
To be perfectly clear, I have NOT heard even the slightest whisper that any of the coaches were personally or romantically involved with any players. Only that they tolerated divisive behavior from some players that they would never have allowed from others.
The rumors have quieted over the past couple of years. So I think that if they did affect the lineup, we're still dealing with fallout from losing experienced high-performers and trying to replace them with youngsters who aren't ready yet and/or not quite as talented.
IOW, if a bunch of high-performing sophomores and juniors (who, as rising juniors and seniors would form the backbone of the next season's team) leave and blow a massive hole in your lineup, it's going to take more than one season to rebuild.
That said, it's still the Head Coach's responsibility to maintain a team culture where that doesn't happen. And the hitting woes have been bubbling for several seasons now. They were just covered up by a few now-departed stars.
