If Hobson gets credit for training Ronnie to victory does he also get the blame for crippling him?
IMO, that primarily came from Ronnie's post-Olympia stupidity.
It seemed self-induced to me. Brian did encourage him - but if you've heard Brian speak about it, he encouraged Ronnie to become a champion. That covers his Olympia run, but I don't think it covers what Ronnie did after.
So IMO, Ronnie is the one responsible for that. It was just his love of hard training that kept him going.
