I think Larry would be a great fit, but the problem is that he's really just a short term coach, guy is 68, and has the track record to be a short term coach for a lot of teams.
If Larry wants to help I don't see it as a problem. Rather he just came to the summer league(assuming there is one?) and/or Fall camp he would have a lot to offer. I'll take a little of his defensive knowledge over Layden's anyday.
