Its way to early, and until teams see doctor reports pre-draft, we have no idea. Teams will take big risks (Philly w/ Noel, though that was also part of a tank strategy that has come to full pathetic fruition over the season, comes to mind) with injured players, but it depends on what the injury is. Re: backs, look at Sully. The risk is more with Embiid b/c he's bigger and would also be a much higher pick, presumably, but it all depends on what condition his back is in. If its dicey, I'd be pretty cautious, even if he drops lower than expected.
