Grayson Allen has high hopes for a lasting NBA career.

The former Duke standout was one of six players who participated in a workout for the Celtics at the team’s facility on Friday and is optimistic about his outlook in this month's draft and beyond.

“I got to learn from coach [Mike Krzyzewski] for four years, so I got to think through the game in so many different roles,” Allen said, via the Boston Globe. “My basketball IQ improved so much just by playing for him. I learned how to prepare like a pro, how to recover like a pro, how to live like a pro while at Duke.

“And I also think I’m in a better spot to land and stick in the league. I think if I would have come out after my freshman, sophomore year, I would’ve been in a good spot, but I would have had to get lucky in a good situation. Right now, I think I’m in a place, I can handle a good situation, a bad situation, grinding through the G League, anything. I can handle all that and have a long-term career at this point.”

Allen averaged 21.6 points per game while sinking 41.7 percent of his 3-point attempts as a sophomore but never quite resumed his star form as a junior and senior.

He also garnered criticism for tripping numerous opponents and was even suspended one game as a junior because of his actions. However, Allen said last month he would address those incidents when he spoke with teams ahead of the draft.

“Every single team so far has just looked at it as competitiveness,” Allen said. “I mean, nobody has, like, scolded me for it or anything like that.

“I obviously have to talk about it and talk through it and say where it comes from and what I’m doing to improve my emotions on the court and stuff like that. But at the end of the day, I’m not getting rid of that, because teams want an emotional and competitive guy out there. You just have to control it, but they want a guy who will bring fire.”

The Celtics hold the 27th overall pick in this year's draft, which is set to start June 21 at the Barclays Center in Brooklyn, N.Y.
