In their defence, at the time of the extension the Leafs were securely in a playoff position, believe it was late December. Everyone remembers the freefall that took place in Jan-Feb-Mar that year. Could not have been predicted, and the Wilson extension was only for one year, which is hardly bad planning.
I can't see him getting too much more than Gunnarsson got, would be surprised if his contract is about 3.5 per year. He is more of a powerplay specialist, while Gunnarsson plays tougher minutes and is overall more important to the defense's core.. Don't get me wrong, good 2nd pairing guy but not worth more than Gunnarsson.. so hopefully he settles for a decent salary. My guess is he is asking for 4+ at the moment, which he will probably not get.
