THE HEAT SAW his drive the first time they scouted Robinson — well, the first time they officially scouted him at a pre-draft workout. “I was familiar with him because of following Michigan in the tournament,” Spoelstra said. “But I’ll be honest, I didn’t think necessarily that he was good enough.” Most agents didn’t, either. Robinson drew interest from agents who represented mostly overseas players. The only NBA agent who showed interest was Jason Glushon.
