Stories are starting to come out......apparently the Leaf players asked him not to talk to them right after games because he was too wound up from the game and would usually said something rude or hyper-critical that would be counter-productive.
Towards the end, Wilson and Burke didn't see eye-to-eye on the type of team they should have. Burke wants a tough, hard-hitting, truculent type of team, and Wilson didn't think that toughness matters as much. Carlyle, on the other hand, agrees with Burke's team-style, and that was pretty obvious when they recalled Jay Rosehill the same day Carlyle was named coach (he was waived early last week- I suppose because Wilson refused to use him).
One of the reasons (not the main reason, of course) Burke decided to fire him was because of the crowd at the Air Canada Centre chanting "Fi-re Wil-son!". Burke said that he didn't want to put him through that again.
No timetable is set for his return. So....yeah.
