Wade would be an absolute dream... Not only is he a solid vet who is perfect under pressure, but, he makes James' leadership abilities much more robust, well-tempered, less-moody, and simply brings with him calmness and stability.
The James-Spoelstra relationship was mediated by D. Wade.
The James-Riley relationship was mediated by D. Wade.
Now obviously, Ty Lue has found a way to take on that role of the superstar whisperer, but nonetheless, James can still be moody. Wade fixes that, bringing accountability, authority, and leadership - and has no problem at all ceding that authority to the proper chain of command (Spo).
I just think Wade being on this team makes infinite sense for the Cavs, even if there is an infinitesimal chance of it happening.
The ways to get Wade on this team:
1) Taxpayer MLE ($3.6M)... Massive paycut for Wade, but we could sign him outright.
2) Full MLE ($5.6M).. Again, massive paycut for Wade, James would need to take a huge one-year paycut as well to make this work, but I have no doubt he would. We'd also lose Mozgov, almost assuredly.
3) Trade Exception ($10M). This is the optimal solution. Cavs could potentially get the 21st pick tonight, if Stein is accurate (and I don't think he is), package that with a future pick and get Dwyane Wade back. Might need to include Shump, but Heat might not want to take on salary. This solution requires that the Cavs end up below the apron, which they can, since James can sign for whatever he wants -- but again, this necessitates James taking less money, and us likely losing Mozgov.
The max offer Cavs can send Wade is $43M/4Y with an option in the 4th year, which isn't bad for a guy who will be 35 by mid-season next year. My guess would be the Heat are likely to offer him $45M/3Y with no options. If that's the case, and Wade envisions himself retiring in 2-3 years, then the Cavs deal is really not much worse at all as he can retire in the final year of his deal and still very likely get paid.
Again... all of this is very difficult to imagine, but Wade and Riley have yet to sit down and hash out a contract. We're about one week away from that happening, and if things go as they did last year, I think Wade bolts.
Lastly, I don't think Wade and Riley like each other any longer... That's just my guess.
