Thanks buddy!

I don't see why. He could sign 8 × 8 with Arizona and take hom more than double what he would on 6 x 6.25 with the Leafs. Takes home 35.43 million on the 8 year deal with Arizona including 26.57 in the first 6 years as opposed to 17.42 on the 6 year deal with the leafs

4.5 million

Ya, can't retain full salary.. has to be 4.5m lol
