I can understand this line of thinking. However, Simmons can't hold out. He'll have to play. If he doesn't play he won't get paid. It'll probably be a breach of contract. He may play so crappy that they trade him like James Harden, but he'll play nonetheless.
I'll still take a team of Joel Embiid with shooters surrounding him over Maimi. I just don't believe in Miami. As I spelled out in other posts, Jimmy's on the decline. I don't believe Lowry will make that big of a difference. The only way Miami improves this season is if Bam, Herro, and Robinson make significant jumps.
