I'll do a full report on Wesley Johnson now that it seems that we could potentially draft him, given our trade for Dalembert.
Physically, Johnson appeals on a number of levels for the NBA. He's very long, and thus appears bigger than your average SF in the NBA. He's a capable leaper (37' vert), has quite large hands, and is wiry strong (he bench pressed the most out of all SFs, yet is only listed at 205 lbs). He's relatively average in his lateral quickness, but is extremely quick in the open court--can really wreak havoc here in the NBA level. On top of all that, he also conditions himself extremely well. There's almost nary a flaw to be found with Johnson physically--he looks big for his position on the court, can jump, is very fast, has length, and never gets winded. Lottery type material here for sure.
Impact-wise, Johnson wasn't a major offensive boon for his team on both the offensive and defensive ends of the court, but he was in the positive. Looking at his individual skills offensively, Johnson attempts to act as an all-around offensive player, equalizing his attempts from everywhere. Johnson takes a chunk of his shots as mid-range J's, but he's below average in this area, although his free throw percentage (77%) gives hope that this can improve. He takes another chunk as three pointers, and while he excelled this year, past years have shown this to be a trouble spot, so I'm thinking he's probably a 34-37% three point shooter in the NBA. Johnson also plays inside as well, and he's a pretty good finisher and in particular, he really looks to dunk, indicating his athleticism. While there's potential to become an all-around offensive player in the NBA, I think, like Shawn Marion, it's more like his best asset is his athletic prowess around the basket, which is then coupled with his decent shooting ability. But based on his current gameface, I think he'll attempt to be an all-around offensive player in the NBA, like Rudy Gay. Other indicators he's best served as an off-ball type is that he doesn't get to the line very well and passes the ball poorly, and a minor gripe is that he gets very few tip-ins despite the athleticism.
Johnson's in the right cloth to be an upper echelon roleplayer type, with middling possessions and a middling scoring rate for the NBA. He's also an above average rebounder for the position, and can gobble rebounds on both ends of the court. Defensively, while he has lottery-type defensive tools, he isn't much of a stealer and doesn't yield too many tip-ins, unlike someone like Shawn Marion--however, he's an excellent shotblocker for the position. Based on his defensive impact, I'd still say he's a little raw right now on this end of the court--he has tons of potential based on his shotblocking and physical tools, but Rudy Gay was the same way, and no one's calling him a defensive stopper.
Johnson's appeal, as mentioned above, largely stems from his excellent physical tools and his imposing of that athleticism through the form of dunking and shotblocking. He's certainly an athletic crowd-pleaser type, and on top of that has a decent shot and a foundation of an all-around offensive game, even if it appears to me that it's raw around the edges on both ends of the court. Johnson certainly has limitations both skillwise and imposing his physical tools: for the former, his jumper appears to be more solid/good than great IMO, and he doesn't get to the line much, intercept much or yield much in tip-ins for the latter. That probably makes his upside more in Rudy Gay territory above anything else, and he'll probably take his game that way.
