If Embid's medicals were to clear him, of course you make that trade. You get it done immediately, before the 76ers have a chance to change their minds.
At the 32 minute mark these dudes talk about going clubbing with Embiid on Saturday. Sounds like he's fine:
http://www.barstoolsports.com/philadelphia/bs-sports-life-podcast-the-time-we-partied-with-joel-embiid-and-why-nerlens-noel-hates-my-existance/ If I'm Hinkie, I probably don't move anyone right now... especially for a bunch of mediocre unknowns from Boston. Instead, I roll into next season with a 3-man big rotation of Noel, Embiid and Okafor. It doesn't matter if it doesn't work, because the team is in for the long haul. They can split the 96 minutes at PF/C and each play 32 minutes each. See what you got with them. See if one starts outperforming the others. See if having Okafor vs Embiid in practice every day causes one to rise above the other (I think Embiid has a much higher ceiling, honestly). See if Noel learns some post moves from the other two. It's a heck of a luxury. Hinkie will hold all the cards... three of the best big man prospects in basketball. And then watch as every team in the league starts offering overpays to land one of the phenom centers to build their franchise around. Why bother trading any of them right now? Points guards are a dime a dozen in this league. Legit bigs?... rare.
Someone will be willing to give up a star at a different position. Like I said in other threads, if you're Toronto, are you really going to pass up a shot at the next potential Tim Duncan by refusing to give up DeMar Derozan? No. If you're the Spurs and you strike out on Aldridge this summer, do you give some real thought into moving Kawhi Leonard for one of Philly's phenoms to carry Duncan's torch? If you're the Cavs and LeBron's boyfriend decides to join the team... do you look at the makeup of your roster and decide, "you know what... as much as I love Kyrie Irving, we could really use a phenom big ... let's move Kyrie for Embiid/Noel/Okafor"... If you're the Bucks, do you look at the makeup of your team... three quality SF prospects (Middleton, Parker, Giannis) and decide, "you know what... as much as we love Giannis, we're a center away from being legit" and move one of them for one of Philly's bigs? Philly can take their time with this. I dont' see any scenario where they dump one of those guys for a package of middling draft picks + Marcus Smart. That's a weak offer.
