I have not been impressed with Dimel this season. I think my biggest concern and disappointment regarding Dimel is that I can understand us still losing and still having certain struggles, but with us having such a veteran staff and Dimel coming from the Bill Snyder tree, I did not expect us to be so undisciplined, have such poor game management at the end of multiple first half's, and us not be as well organized as one would expect. Those are things that don't take talent to improve on and since we have had such major/consistent issues with them so far this season, that gives me big concerns regarding Dimel.
That being said, this team was bad long before Dimel arrived here and he has essentially redshirted all of his high school recruits so far, which means that we still have not even seen 90% of the high school kids that he has brought in. As an example, Dimel has signed 9 3-star high school players since he arrived and we have not seen any of them play yet. So I can give some understanding towards assigning a bit more of the blame currently on the players that he inherited instead of Dimel(I.E. only 4 starters on the offense right now are players that Dimel signed). The problem is regardless of the players, we should be seeing more consistent improvement.
As a final comparison, Rice has not won a game this season, yet if you compare us to Rice this season based on the "eye test", I would feel more confident about their rebuild at this point than our rebuild.
