yep...a lot of people after this sequence of events:
Embiid suffered a stress fracture in his back in March 2014.
[19] He missed that year's
Big 12 tournament and
NCAA tournament. Kansas lost in the second round (round of 32) of the NCAA tournament.
On 26 August 2014, Embiid signed his rookie scale contract with the 76ers.
[23][24] He was later ruled unlikely to play at all in the
2014–15 season due to the broken navicular bone in his foot.
[25] After missing the entire 2014–15 season, it was announced on 13 June 2015 that Embiid had suffered a setback in his recovery after a CT scan revealed less healing than anticipated.
[26] It was later determined that Embiid's chances of playing in the
2015–16 season were slim following a second round of surgery on his right foot on 18 August 2015.
[27][28] He missed the entire 2015–16 season.
