Even the players inside the Orlando camp are uncertain about their NBA future, so the odds don’t favor an outsider like Butler. He needs every jump shot and repetition in the weight room to remove question marks from his scouting report.

Scouts wonder if he’s tall enough to play in the NBA, since he stands only 6-foot-2, small by shooting guard standards. Others ask if he has enough experience at point guard, a position he would likely play in the pros even though he hasn’t started there regularly since high school. Many insiders think he’s only gotten this far in the draft process due to his role on a Mason squad that busted brackets last March.

“Some people love him, some are lukewarm,” said one Eastern Conference scout. “He’s on the bubble.”

Butler knows the obstacles ahead of him. He just wants to prove himself on the court.

“I’m hoping to play on a summer league team and show the NBA what I can do,” he said. “It doesn’t matter what position I play, as long as I make it to the NBA.”

Butler was invited to the Portsmouth Invitational Tournament in April and was pleased with his play there. The Wizards also worked Butler out at Verizon Center. According to Butler’s agent, Andre Buck, the team was impressed with his client.

“Specifically, I was told that they could count the number of shots he missed on one hand,” Buck said.

Despite his shooting skills — Butler averaged 11.8 points and shot 37.3 percent from three-point range in his senior year — scouts believe Butler will only play at the next level if he becomes a better passer.

“Mainly, I’m trying to improve my point guard skills, because I haven’t played it in so long,” Butler said. “It’s not that hard, because I played it for so many years in high school. But really, I’m just waiting for my opportunity to come. When it comes, I need to show that I can play.”

He knows his best opportunity yet came during Mason’s unexpected postseason run.

“I know I would not be in this position if we had not made that run,” he said.

Now is the time for Butler to take advantage of that success. Though he will likely go undrafted, he’s hoping to sign as a free agent after the summer league is over. If he does not sign with an NBA team by the end of the summer, he wants to play professionally in Europe.

Butler credits Mason’s Elite Eightvictory over Connecticut — the Patriots’ fourth win in an NCAA Tournament run Butler said “changed the face of basketball” — as the source of his confidence.

But that confidence can only take him so far. The scouts need proof that he is NBA-ready, which is why he’s in Orlando, waiting to showcase his skills. Maybe he doesn’t have an NBA game yet; maybe the NBA can wait. For now, he simply wants a chance to play.

Said Butler, “We’re just trying to get on the stage first.”
