I would think a part of this has more to do with staggering these deals into different off-seasons.
If Mo is in for 6 years, that puts a five year timer on the plan. You either have gotten good enough that he is signing on July 1 after the 5th year, or you have dealt him at the draft.
I am still hopeful they can get 8, but if you do what you should do between here and the end of these contracts on the big 3 it really shouldn't be that disadvantageous at the end of this. He also likely actually has the lower growth number.
If it is down to paying him 9.1 over 8 and finding a way to get some of the salary off, heck LTIR Husso justifying taking his groin slow then Yzerman should be able to find a way. The Faber contract has hurt them a little here. I thought they would be able to argue some of the circumstances around it like they did with Stutzle and Ottawa but maybe that isn't meant to be.
