I've defended Milroe to some degree, but I do agree that CKD not feeling like he could bench Jalen for whatever reason is worrying. Either he felt too grateful to Jalen for staying and holding things together. Or he doesn't have faith in the backups or worse he felt he would lose the team or didn't install a gameplan for the backups.
Give it a year or 2. I have a feeling there's more to it than we're privy to, but things usually come out eventually. I don't think it's as simple as DeBoer being so incompetent that he refuses to makea QB change. It's pretty clear at this point that some sort of deal was made to hold together the roster that involved Milroe being the unquestioned starter. But even if I'm wrong, and that wasn't the case, there are plenty of other reasons why he wouldn't make the change today. For starters, the offense we have installed is more suitable to Milroe than it is for Simpson. Even if Simpson came in, we wouldn't be running the DeBoer offense, because it's not installed. It would be this shell of the offense that we had to create for Milroe. There's also the fact that Ty has basically zero meaningful game experience, and not much experience with the first team, and we'd be throwing him to the wolves. Maybe it's best that he didn't play. In the worst case scenario, you'd be killing the confidence of your presumed starter for next year, and in the best case scenario, he comes in and wins a meaningless bowl game that half the fanbase claimed they didn't even care about until we lost. I'm just not sure it was worth it.
And if we're being honest, I think I'd have been a little more upset if he did make a change today, after not doing so when it actually counted and we had a shot at the playoffs.
