If you're really going to look at freeing up cap space and having an overhaul - I'd be looking at Manny/Leo at RB. If Manny isn't happy playing there I'd actually look to release him. He's had a shocker this season when asked to do something different to the basic role he's had previously and he's definitely on good money plus there would definitely be someone willing to take him on in Aus.
That's a good point. If the owners really want to talk tough they could say to Manny "you will play RB" and then release Bertos.
