I wouldn't waste my time with Betts. He's a 30 year old rb coming of an ACL and MCL injury. He wasn't anything special before those injuries and a year younger. He may not even make the team.
Except for the ACL and MCL (which is a significant injury), sounds like a description one could have read about Mike Bell last preseason.
For some reason, NO doesn't seem to want to give Thomas "bell cow" type touches, and they limit his touches. Perhaps Betts is going to be a part of that this season. At the very least, it seems too early to surmise that he might not even make the team.
