Should the Colts cut him?
I don’t know. It seems extreme to me.
Maybe they can move more slowly in that direction. He wouldn’t have a say in the team putting him on IR, and for the price of his base salary ($1.308 million) they could ensure he doesn’t play this season and buy time for him, and them, to make the more long-term decision.
That’s really the best way to keep him from playing football this season.
