The Marcus McMaryion discussions I don't understand.

The thing that bothers me most is we will never know the answer to that statement, and I think he deserved a shot, certainly not demoted to 3rd string. Andersen is no Tedford and he's proven he can't develop Qb's, until he proves me wrong I say 3M got screwed. To know the real reason you'd have to be a fly on the wall

You shouldn't be including his 2015 stats.  Those really bring his numbers down quite a bit.  

The facts are that he had, what, 6 practices with the "ones" in the past two years, and still outperformed this coaching staff's "hand picked" QBs - by a mile.  

Look at his numbers from the WSU and Arizona games.  We hear a lot of people talk about "ceiling" when getting excited about Luton, but it's highly likely that Luton will never have two games as good as what McMaryion had in those two games.  We're talking vs Pac-12 opponents, not FCS or group-of-five teams.  None of the QBs you've listed (or any other QB to have played NCAA football in the last 5 years) has had a higher NCAA efficiency rating than McMaryion did vs a P5 team.  Admittedly it's a flawed stat, but it is the official NCAA statistic.  

To be honest, it means more about how poorly our coaching staff handles QBs than it does about one guy.  

In reality, we would have been better off last year with Seth Collins remaining at QB than going to DG.  Collins was better than DG as both a runner and a passer.  That it took 2 injuries to get to our best player at the position should be embarrassing to the staff.

The other piece is that McMaryion was the only QB on the roster who actually posed a "dual threat" ability.  DG can't pass, and Luton can't run.  SaveSave

Limited practice with the ones. Put in at bad times.... game one of his career he is put in and the coach calls a pass out in the flat, receiver bobbles it to a defender for a pick 6 - Demoted. After that he's put in at the end of games when the offense is already in trouble and gee it doesn't work out... 3rd and long is no time to come in and somehow fix what your starter set up all in one play.

All of t hose QBS the OP mentioned had weeks of practice with the ones before having to throw a pass in a live game situation. Completely different situations.

*Not only a pass out in the flat on his first play under the new system, but I believe backed up on his own 3 yd line. And, if you were there or know the "story" was not informed it was his series until time to go in... zero warm up throws since pre-game. Benched and where the disgraceful treatment escalated. Teacher of men my arse!

You need to re-read. I said Collins was better than DG.

If you watched the QBs last year, McMaryion was sitting either through spite or extreme incompetence. Neither is an appealing answer.

He handed him the job? Huh. All along I thought he won it in the eyes of the coaches. Btw, why aren't we talking about the defense? That's the problem. Maybe the D was all broken up about 3M getting the shaft, focusing on that instead of their real problems. Not likely.

Maybe so, not going to argue that. But that was their determination.
