I understand that coaches need to stand by their players if/when they're struggling so that you can maintain confidence, but you have to wonder about Greer's state of mind right now. He's been out there for the majority of three games, and the offense has been anemic. But the killer for me was the game against SMU - there were several times when our defense set up the offense with perfect field position, and we kept settling for FGs. It's great that we have a good kicker who should be able to win us close games if needed, but in other games, a better team will have snuck that game if they scored TDs rather than FGs.
When the same wide receivers who kept missing with McNulty and Greer are hitting with Dajon, then you have to think it's the QB throwing the ball rather than the WR not catching the ball. Not to mention the threat of even a half-decent passing game will open up the running lanes for our cadre of RBs.
If Mac truly wants the program to grow, and #hit30k and all that nonsense, he can't keep trotting out Greer and expecting people to keep showing up. The student body is still quite fickle - one or two more underwhelming offensive games and all the hard work that was accomplished last season is going to be lost, and there's no telling how long it will take to bring back that level of excitement around the program. Stubbornness can be a good trait, but in this instance - it's quite clear - Greer isn't the answer at QB. Neither is McNulty. And when you have a talent like Williams, it's a travesty to waste him in garbage time, especially when all he does is show up the 1s.
Point being: Williams has to start vs Nicholls State, then evaluate from there. If he goes 2-10 for 10 yards and an INT, then sure, go back to Greer. But if he goes 8-15 for 90-odd yards a TD or two, then there's your answer. If it truly is a maturity issue, then like a previous poster said - pull him into a one-on-one meeting with Mac and/or Chico and let him know that it's his team and to start acting like it. He sounds like the sort of player who thrives on responsibility and if knows he's going to remain marginalized, why should he bother? Especially when - right now - he's head and shoulders above the current QBs. There's hope that he was put in over McNulty vs LaTech though.
My preseason prediction of 4-8 looks increasingly likely if Mac persists with Greer, and may end up losing the locker room if Williams continues to show up on the field.
