I think, for the most part, JR is a hands off owner. The only time that I believe JR has been hands on has been during transitional phases - Leading up to Fox's lame duck year and forcing Hurney to release older players, preparing for the lockout, etc. During normal seasons I think he allows total control to the GM's regarding contracting and player personnel.
I have hard time believing this only because of how involved he is in every negotiation in the NFL. Would a hands off owner be knee deep in locking the players or the refs out and the subsequent negotiations?
