Fran Fraschilla established himself as ESPN’s best voice on the NBA draft based on his forecast of the No. 15 selection in 2013, and nothing has happened since to knock Fraschilla off of that perch.

“Great talent with a great feel for the game,” Fraschilla said of Giannis Antetokounmpo. “In the long-term picture, this kid has as much upside as anybody in this draft. Handles the ball well and is a willing passer.”

Fraschilla attends camps highlighting the nation’s top high school prospects, does color commentary on college games for ESPN and goes overseas to scout international talent. He recruited well as a college coach primarily because he knew how to judge talent.

I thought he was the perfect person to weigh in on the Celtics’ four draft choices and he obliged in a telephone interview.

Fraschilla on No. 14 Romeo Langford, age 19, 6-foot-4, Indiana: “Romeo is a piece of NBA silly putty. We’ll see if the Celtics are able to mold him into the type of player they hope he can become. It’s going to take a symbiotic relationship between him and the coaching staff, and particularly whoever is assigned to begin to work with him on his shot. It’s going to have to be an organized, structured plan, which given what I know about Brad Stevens, I’m sure that’s going to be the case. I’ll tell you about two mechanical flaws: He pulls it back over his head, and he has a terrible guide hand. His left hand is always moving, but they know that. It’s going to take sweat equity on Romeo’s part, and the indications I’ve gotten are that he’s a good kid. If he doesn’t allow himself to be molded in the right way, he’ll just be a journeyman player or a bust. He has attributes that can turn him into a good player. He has a knack for scoring. He’s a hard driver to the basket. He plays down hill well, especially going to his right hand. He’s a project, a rich project. Now the question is: Does he want to be in the NBA or does he want to become an NBA player? There’s a difference.”

Fraschilla on No. 22 Grant Williams, 20, 6-6, Tennessee: “Grant is another project, and that’s not to be critical. He’s a very bright basketball player. He’s a very bright young man, and he’s figured out how to become a very good college player. The next step for him is to figure out how to become a really good NBA role player because I don’t see stardom on the horizon for him any time soon. When I was at Tennessee in October, Rick Barnes compared him to P.J. Tucker. The difference is P.J. had to go overseas and learn how to become a perimeter player and he learned how to shoot the 3-ball. He never attempted a 3 at Texas (playing for Barnes) and now he’s known as a 3-and-D guy, one of the best defensive players in the league and an excellent open shooter. Grant has to figure out what his NBA strengths are going to be and become that player, and he’s bright enough to do it. It would be similar to making a transition from defensive end to free safety. But he’s got the smarts and the athleticism to do it. There have been a lot of high-character players coming into the league in the recent past and Grant is in the top 1 percent of that type of kid. Now it’s a matter of making the adjustment from college post player to a a more versatile NBA forward who can play a little more away from the basket and go post at times.”

Fraschilla on No. 33 Carsen Edwards: 21, 6-0, Purdue: “It’s a luxury to have a guy who can come off the bench and get you 12, 14 points in the second quarter and he’s that kind of player. Now he’ll have moments where he may go 0-for-a-week, but having a guy with his shooting ability fits perfectly for that role, scoring in bunches off the bench. He was overlooked in high school and still plays with a huge chip on his shoulder because of it. Because he had 28 3s in the NCAA Tournament, usually we would call it recency bias, but that’s kind of the player he’s been. I saw him score 40 at Texas in December. Purdue lost four starters and he was able to take the team one step farther than that Sweet 16 team. He basically put that team on his back. If not for one magical Mamadi Diakite shot (at the buzzer to force overtime vs. Virginia), Purdue goes to the Final Four. Carsen reminds me of a kid who was undrafted out of Baylor, David Wesley, and had a long (14 seasons, three with Celtics) NBA career. Carsen has skill and strength. He could drive his college coach, Matt Painter, crazy once in a while with his shot selection, but Coach Stevens and Matt Painter are very close. Brad knows everything about Carsen. Great kid. Highly competitive.”

Fraschilla on No. 51 Tremont Waters, 21, 5-11, LSU: “Nobody in college basketball had more talent at the point guard position than him. He has tremendous speed, passing, shooting the 3, defending, moxie, a high basketball IQ, it’s all there for him, except size. He has NBA talent. He just doesn’t have NBA size, and that’s why they were able to pick him up in the second round. In the NBA draft, players are taken on potential or production. He was taken on production and some might not like his potential because of his size. Take Draymond Green, he wasn’t drafted until the second round because teams overlooked his production and didn’t see the potential. With the Celtics this year, they took Romeo on potential and the other three on production.”

Drafts are so compelling because they allow all of us to guess as to which players were taken too soon, which too late. For example, we can all guess which of the C’s four selections will score the most NBA points during his career.

My guess: Edwards, a steal at No. 33.
