AK I think was addressing lack of accountability among the players. I'm going off my somewhat hazy memory here. He never mentioned the coaches by name, so it would depend on what you think he was addressing. MT is a complicated situation because I think he was pointing more at the medical staff than the coaches. I've never seen him say anything bad about Allen.
Winston was injured at the beginning of the season and players/coaches sometimes disagree about how to handle the timing and circumstances of returning from injury. Dalton hasn't been great, but he also hasn't been terrible. I would have liked Winston to return, but he really didn't look good at the beginning of the season and the injuries unfortunately derailed his season for the second year in a row.
All that said, and like I stated earlier, I'm not on board with sticking with Allen another season. But if the front office gives him a second season, it's playoffs or he absolutely would have to go at that point.
Edit: fwiw, I think Loomis and Gayle will give some weight to the evaluations after the end of the season. I suspect players will have plenty to say one way or the other at that time.
