Underclassmen have until April 28 to declare for the June draft, but Smart's decision and announcement will likely come before that.
And he's not the only one to keep an eye on.
Although some may scoff, there's still a slight chance that either (both?) Markel Brown or Le'Bryan Nash also declare early.
Nash wouldn't commit to a return for his junior year, saying he must first research and discuss with his coaches and mother. But some of his other postgame comments clearly indicated the way in which he was leaning.
“We're going to have a better year next year, now that we've got this experience,” Nash said.
The 6-foot-7, 230-pound Nash has the prototypical pro body, but his stock has plummeted through two inconsistent seasons.
Markel Brown, on the other hand, has seen his rise, from relative unknown to fringe first-rounder. One online mock draft had him going as high as 23 recently.
But like Nash, Brown seemed to favor another year of grooming in Stillwater.
“I'd probably go if I was a guaranteed top-15,” Brown said. “Right now, I haven't been that high, so it's still up in the air. I feel like I'll come back.”
Either way, for all three, we should know in the coming weeks.
“It's all of their dreams to play in the NBA,” Ford said. “It's their dream, just like any Division I kid. If that time is now, then it is … We've got to do what's best for these kids.”
