I think Calhoun used to let his warrior players highlight their potential NBA position in their senior year. Burrell became more of an outside shooting 2 guard his senior year. The same think happened with K Free. He was a warrior down low, but he had no shot at the NBA with that game. His senior year I remember him playing outside the paint a lot more.
Re Burrell's athleticism, I played tennis with a number of the players in 1992. All were decent guys. Most were terrible at tennis regardless of being D1 athletes. It was clear that Burrell was the most natural athlete of all of them. I tried to lob over him once... once.
Someone stated that he remembered Toraino's famous dunk seeming more spectacular. I remember that one, and Burrell's alley oop at the first Gampel St. John's game being fantastic, but I agree that they seem more commonplace in highlights. My theory is that: i) there were a lot less highlight dunks back in the early 90s; and ii) Calhoun's teams, in particular, back then didn't dunk as much as other teams. I know he didn't tell them not to dunk, but I'm assuming if they missed they knew they'd get the treatment (probably right on the court).
