I'm thinking that would be a good lineup as well.
Stephenson
Kobe
Melo/Ariza
Randle
Pau/Monroe
Farmar
Swaggy
etc...
That wouldn't be bad at all. It's also looking like Bosh isn't willing to take quite the paycut that Miami would like him to. Apparently, he's looking for $16-18mil.
I wouldn't hate the Lakers making a run at him if they can't get 'Melo or maybe even instead of 'Melo. Get him out of Miami and I think that he goes back to being the player he was in Toronto, only with more experience.
Randle can back him up or maybe even slide to the 3 spot. I think Pau would re-sign as well.
