I think you have to come up with something a little more compelling. I'd say its on par with Price's season (remembering that I've only seen the latter half of Burgess's season). Price was technically a much better defender (read: wrestler) but in 2007 he still only averaged ~25 tackles a game. So even if you prefer Price's quality over quantity - which I do - do you think that it is enough to make up for Burgess's indisputable advantage as an attacking weapon?
I could believe separated shoulder or damaged joint. But if he genuinely dislocated his shoulder he wouldn't be able to move his arm, unless someone put it back in for him, which I don't recall happening.
Yeah, in which case he didn't 'play most the game with a dislocated shoulder'; he just dislocated his shoulder early in the game. Once your shoulder gets popped back in - either by itself or with help - then it's not dislocated anymore. Still hurts like a bitch of course.
Which is conceivable but putting shoulders back in isn't half as easy as it is made out to be, especially for professional athletes with significant muscle mass around their joint and particularly if it isn't an injury that happens to him frequently. Anyway, tough of him to do so if it is true.
