For my top pick, I'd definitely have to be Hassan Whiteside. The dudes 7'0 265lbs of muscle. 26 years old while only being 3 years pro. So very little wear and tear. Hes an estalished big whos a monster on D. Would easily average double-double's nightly for the blazers. Happens to be the best shot blocking player in the league. He's an unrestricted free agent after this season. Heat couldn't match his offer if he signs elsewhere and they happen to be one of the top teams for being so far over the cap. So for the Heat, throwing/offering him a max would be very problematic; even if Wade is a free agent this summer, he'll for sure be getting another final/last long term deal from the heat since hes their face of the franchise/main attraction for selling home seats.
Whiteside for the Blazers, would give them a true defensive anchor, and really a legit anchor on both sides of the court. Averaging 28.5 minutes a game, he averages 13 pts, 11.5 rebounds, 0.6 steals and 3.9 blocks with a PER of 24.60. Hes already established himself as one of the best defensive bigs and hes only officially started a season and half. So clearly, hes still developing and has room to further improve. Another pivotal thing to point out is his high level of potential on offense. Against the Timberwolves, 22 pts, 14 rebs, 10 blocks. Against the Wizards, 25 pts, 23 rebounds. Against mavs, 25 pts, 19 rebounds. Hes great at scoring/crashing the boards via second chance points. Has a nasty and consistent hook shot and when very close to the rim, undoubtedly becomes one of the harder players to stop from muscling his way to the rim. With Chris Bosh there, Hassan offensive opportunities are limited vs the Blazers where he'd realistically be their 1st option down low. Only concerns with Whiteside, is he seems to be a little immature; though, nothing on Cousins level. I believe with Lillard and CJ being the voice/leader for the Blazers I'd work out, doesn't help help there all near the same age. So with that, it could help provide a context of where in this together.
