My take on Yzerman's view on DBC's deal, is that, in a vacuum, one could earnestly argue for max term and high AVV for DBC. The question becomes, does that term and AVV fit with Yzerman's timeline for the Wings? Yzerman could easily be thinking that he likes DBC and that it would be nice to have him, but only he knows what his next moves are and how the speculated contract demands will affect those plans.
His offer probably comes with the qualification that here is what I can offer while still allowing me to go forward with my plan, if you're on board, great, if not, the timing isn't right.
