Beginning with the Brooklyn Nets' 27th overall pick, I could see any of the remaining first-round picks being packaged in a deal to acquire a role player that could contribute to these teams immediately. I could envision this Nets pick being packaged in a deal with DeAndre Jordan to acquire a more impactful player.
Assuming for now that the Nets keep the 27th pick though, I have them selecting Charles Bassey out of Western Kentucky. Bassey is a 6'10" center with a 7'3" wingspan that served as the team's anchor on both sides of the floor. If the Spurs were to acquire a late first-round pick and are looking for a center, I have gone on record in the past saying that he would be a great fit with the team.
The fact of the matter, though, is that the Nets need defense. This past season, Bassey was one of the best shot-blockers and rebounders in the entire NCAA. He also had the second-best player efficiency rating in the entire NCAA only trailing that of Iowa's Luka Garza. His motor is among the best out of all big men available in this year's draft and there's evidence that suggests he could develop a three-point shot.
Bassey's injury history is probably the only thing placing him as low in this mock as he is, but considering what he was able to do in his comeback season, I'm not worried at all.
