The guy has good hands, a good shot and showed really good anticipation/hockey sense back in 10-11. The word is last year he came to camp out of shape and he was never able to find his game after that. His skating is average at best, he's not a great passer, and he appears completely lost defensively most of the time. He's still young enough to get his head screwed on straight, and if he does I could see him finding a niche as a Michael Ryder type player, but if he's not scoring goals he's a total liability.
IMO what's really holding him back as a goal scorer is his lack of a one-timer. For a guy with soft hands and a great release, he sure flubbed a lot of setups from Spezza.
Count me as one Sens fan that didn't like us buying out Butler. I think he still has a shot at being a 20 goal, 60 point type player, especially with good linemates. I think this will come back to bite the Sens where they sit.
