I'm glad they cut him. Having standards of conduct is a good thing for a team and I applaud their actions at that place in time.
Bringing him in now would make sense, though, IF they think he would upgrade them. Keep in mind one of the rumored reasons he was cut (in addition to the allegations) was that the
Rams didn't project that they'd need him. Even with DE out for the season that does not necessarily mean they see a place for him on the roster.
