It's all speculation until draft night, so what else can an overzealous Sixers fan do till then except explore plausible what ifs.....
If rumors are true that Milwaukee or Philly has spoken to Cleveland about acquiring #1 pick, then I assume it's us b/c Milwaukee is hesitant to risk another investment in a disappointing big man. They have to live with the toxic guaranteed contracts of Ersan Ilyasova ($8 million/yr for 3 years) and Larry Sanders ($11 million/yr for 4 years). Plus they still have high hopes for John Henson to develop. So I think they're perfectly content at #2 to take Parker or Wiggins.
Whereas we are in great shape to offer a top 3 pick, Thadeus Young, a few 2nd rounders, and absorb the undesirable guaranteed contracts of Jarret Jack ($19.4 million guaranteed over the next 3 years) and Anderson Varejo ($9.7 million guaranteed next year). We get Joel. The Cavaliers still get Parker or Wiggins, a starting PF/SF in his prime who is $4 million cheaper than Luol Deng - should they choose not to resign him, and cap relief to go after a superstar or group of veterans that their new coach will - not inherit - but pick himself. Irving all of a sudden likes his chances of winning sooner rather than later and signs a LT deal. Looks like a win-win to me IF Cleveland is not in love with Embiid AND they can attract quality veteran players to the great state of Ohio.
Regarding the likelihood of a happy Joel-Noel co-existence? I don't have an answer. There is not an insignificant risk of disappointment. Brett Brown will have his work cut out for him. But if the Popovich protege can earn his stripes, I can't help but consider the real possibility that two ultra talented 7 footers - who can enforce the largest no fly zone in the paint man has ever seen, move with more lateral quickness than Jabari Parker, have comparable freakish athleticism to Andrew Wiggins, and can finish a fast break - could potentially...POTENTIALLY...revolutionize the game and usher in the next NBA dynasty. Dare I dream.
