I made quite a few posts about Swanigan when he was at Purdue. He was one of my favorite dark horse candidates who might slide into the 1st rd. As someone mentioned earlier, he's got quite a story, originally weighing around 400 pounds, he completely remade his body finally got down to around 250 pounds. If I were going to compare him to someone, and I have in the past, it would be a shorter version of Cousins. He's very skilled and was a double/double machine his sophmore year at Purdue and almost a 20/10 guy, avreaging 18.5 pts and 12.5 rebounds a game.
Like Cousins, he can play bully ball by backing you down to the basket and scoring. What made in more interesting to me was his ability to step out beyond the 3 pt line and shoot the ball. He averaged 44.7% from the three, while averaging 54.8% overall. Add in that he's an excellent passer with terrific court vision and you have a player with quite a bit of potential. The downside is that he's about as athletic as Cousins. Doesn't have great hops, (29" max vertical) or great lateral quickness (one of the slowest times in the agility drill at the combine). But, he does have a 7'3.5" wingspan, and a 8'11" standing reach.
Does all that add up to a productive NBA player? I can't answer that, but I wouldn't bet against him. Let me put it this way, if Jack Cooley can play in the NBA, then Swanigan might end up being a star. Someone did a Reggie Evans comp, but I think Reggie was a little better overall athlete than Swanigan, but Swanigan is far more skilled than Evans. Particularly on offense. It should be interesting to see how he pans out.
