Size? You mean Pau?
Miami would run them out the gym. The Lakers have no answer for LeBron while Dwight is showing without spacing he can be doubled, taking him out the game. Kobe turned the clock back the wrong way and ended up back in last year.
Bosh is balling and would just run around the Laker bigs. Miami has a bench full of deadly shooters. Wade showed last game he is coming back to form with his 28. LeBron is just on another planet and come playoff time, that championship D will be back along with this year's league leading offense.
