If it gets interesting at No. 4 -- and it does -- it could get really interesting at No. 5. Sources said Toronto president Bryan Colangelo is all-in on the team's new defensive-minded approach, and he is considering taking Biyombo there despite the widely held belief that the athletic defender/rebounder/shot-blocker would go lower. The Raptors, of course, just hired Dallas assistant and defensive specialist Dwane Casey as their coach and are clearly looking to improve significantly on that end of the floor. Colangelo has considered moving back to take Biyombo as well. Connecticut guard Kemba Walker, San Diego State small forward Kawhi Leonard and Czech Republic forward Jan Vesely remain possibilities for Toronto, but it sounds as if the love affair is with Biyombo. This comes as a surprise in light of Biyombo's recent workout at Adidas Eurocamp in Treviso, Italy, where he was even worse than expected on the offensive end and appeared to have hurt his stock.
