Needless to say, when a player suddenly cancels scheduled workouts, people wonder why. And, generally, it's because someone promised they'd draft that player.

It appears that is the case with Syracuse guard Dion Waiters, who canceled all upcoming workouts.

Given where Waiters is expected to be selected and the Suns' need at shooting guard, it's possible they're involved.

Tweeted ESPN NBA insider Chad Ford:

Lots of teams buzzing about a Dion Waiters promise. Teams say he's canceled all upcoming workouts. Blazers, Raptors, Suns all suspects

Friday morning, the plot thickened, as Toronto GM Bryan Colangelo vehemently denied the draft promise to Waiters came from him.

According to Steve Kyler, the editor and publisher of Hoopsworld.com:

Raptor GM Bryan Colangelo was genuine in his denial on Dion Waiters... went on a rant saying "Why Me? Why am I the guy making promises"

Sources say Waiters was immediately on a flight home to Philadelphia and has indeed shut down workouts... sources peg Phoenix as the spot

Oh, but that may not be the case at all. Arizona Sports 620's John Gambadoro is reporting that while Waiters may indeed have a promise from someone, it's not the Suns.

Suns are not the team that has a promise deal with Syracuse shooting guard Dion Waiters

So, through our advanced methods of deduction we've narrowed it down to Portland being the team that promised to draft Waiters. They are selecting 11th -- ahead of the Suns -- so if that's the case it wouldn't matter if Phoenix was interested or not.

The 6-foot-4, 215-pound Waiters averaged 12.6 points per game for the Orange last season, shooting .476 from the floor and .363 from three.
