The Miami Heat shouldn't overthink the big decision awaiting them on October 1. At least for now, the Heat can't give Tyler Herro the big contract extension he's going to be seeking. He's a really good player, but not a great one. And for the money he's going to be asking for, he'd have to be a great one before it becomes an overpay.
The Heat can't afford to find themselves in that situation, one that would all but trap them in NBA mediocrity for the foreseeable future.
Herro's Achilles heel has always been on the defensive end of the floor.
