It wasn't in practice, it was a cheap shot from the back after practice. You are correct, he was suspended, but you are trying to make a point that Payton didn't put up with that stuff, but he did let MT get away with some antics. Now others were shipped out of town because they weren't on the same production level as MT.
It's going to be a bittersweet day with MT is officially not a Saint anymore, but it will be a lot more sweet so this team can move forward. Some fans will be butt hurt, but they can still follow him on X for entertainment.
