I don't believe I've said that his roster is weak, just pointed out that without a healthy Wade, it probably isn't the best roster in the league. Teams are literally playing off him like he was Tony Allen.
And the Spurs can overcome Paker having an off game when two role players combine for 50 points and a crazy shooting night. I don't care how well James, Wade, or anyone else plays if Green and Neal continue to make 13 out of 19 threes a game it isn't going to matter.
I would counter that with if the heat continue to play poor defense and give open looks to shooters, then yes, it isn't going to matter.
