The big issue I see is that Milroe is hiding some other issues.
If you just go it's all Milroe's fault, you are kind if ignoring other areas of concern. For instance, there was no established running game this year. When you have a quarterback that's unreliable, that's exactly when you should be investing a lot of time and effort into getting it going. Instead, Alabama has a running back that averaged a perfectly respectable 5.7 per rush leaving because he only got 79 carries.
This team is set up to put everything on the shoulders of the QB and when he doesn't play well, we can all blame the QB. What we're not doing it asking why everything was put on his shoulders in the first place. The offensive coordinator is mediocre, was fired because his offense sucked at Indiana and is only here because he knew DeBoer. That's a problem, there are other problems to but unless Penix is going to come back to college, I'm not sure DeBoer's offense is going to look like what we think his offenses look like...
