Ziggy kind of touched on most of it.
The Kings got Cammalleri to sign early by promising him the opportunity to play with Allison and Deadmarsh and have Palffy move to another line to balance the scoring. Well this did not make Allison very happy, not only did he not want the rookie on his line, he went out of his way to make him feel uncomfortable at training camp. Never heard anything about the alleged incident with Norstrom, but it wouldn't surprise me at all if it were true. Jason Allison was the Jack Parkman of the NHL (my second Major League 2 reference of the week)
It's one thing to be money hungry me first players like Blake and Smyth, as much as I disliked both, they were respected and liked by teammates. Allison was not only a me first, money hungry player, he was also apparently universally disliked by teammates in every place he went.
Wonder what that clown is up to these days.
