I don't think he is a long-shot to make the NBA at all. In all likelihood, he won't be a high first round pick, but he has the size, strength, lateral mobility along with superb offensive skill to have a long career.
I looked at each of the NBA rosters on ESPN and saw how many players there are within 10 lbs. and 1 inch of height of Adama to see if his body type is common. Only five teams did not have a player that falls within this range. Denver has 5 players that do. Several of the players are NBA starters. Many of the players have had 10-plus year careers and have made huge fortunes. Many of the players do not have the reputation as shooters. 4 of them are listed as starting centers or play near starters minutes.
Some have said that Adama is significantly shorter than his listed height. I'm not sure that this is correct, he was certainly about 2 inches taller than the Miami center who was listed as 6' 7". I guess we will see when the combine measurements come out.
Go Adama!
