I wonder if we will see something like the Ellis deal where they go to 8 just to get the AAV down. If they front load a $6M-$6.5M deal, he likely outperforms the cap hit for the first several years, and maybe he is Patrick Marleau esque and ages well later. They are similar in that they are bigger guys with fantastic wheels.
The other side of that coin is that if he keeps playing, but declines, he will be overpaid, but he gave the team a break when it mattered. Also, with signing bonuses the team could likely move him to a non-cap team since he will make far less than the cap hit. Finally, they could gamble heavily on paying him big money on that contract now, and having a compliance buyout on the new CBA if there are any significant changes. If nothing else, maybe it give the team the best shot to compete for a 2-4 year window, and they probably aren't completely screwed after that as long as they only have one or two contracts that are a little ugly at that point.
