BJS is good - but Lee will stop him in the later rounds. I suspect Lee may lose a few early rounds, before ratcheting things up and winning rounds before stopping Billy Joe. BJS is better than he gets credit for - but having not mixed outside of Euro level will hurt him on his first world level fight. Just as people don't know enough about him to rate him, they also don't know enough about how he reacts when really dragged into deeper waters - he hasn't been TRULY tested. Lee gets under-rated because of his stoppage loss to Vera - which was a fluke to be fair, and reversed, and also his loss to a huge JCCjr, who is basically a light heavyweight anyway. Andy Lee is a career middleweight, and totally comfortable at the weight (as in he isn't big or small for a MW).
It wouldnt suprise me if this bout was a fixed draw......with the rematch taking place at the original venue in ireland
