If this is the case, Wally needs to get in the weight room yesterday.
Wally is as big as curt, JHR, Jamar, etc.
Getting bigger would be great, but don't act like he is a waif or some skinny kid.
quickness/agility and hands drills are needed
All true, but until about 10 games ago this was needed for JHR too.
Wally has been put in his place... and there would obviously need to be some reconciliation between the staff AND the team. But if Wally plays by rules and agrees to the path of reconciliation laid out by Frank, the team, the school, etc... and this is the place Wally wants to be, then by all means, let him back.
I certainly agree with Zacker however: If your going to let Wally comeback, I don't think you can even consider jettisoning anybody on the current team just to open up schollys without completely losing credibility with the players.
