His PTS and REB were very solid. As was his FT%. His usage rate was extremely high and actually led the NBA during the pre-season. Surprisingly he also wasn't a very good shotblocker. In fact, the much maligned Zeller had more blocks in less playing time. His turnover to assist rate was atrocious. He didn't record a single assist in over 100 minutes of total playing time. He fouled at an extremely high rate. He also had a very poor FG% for his position, but wasn't helped by his tendency to shoot them (1 attempt per game), when he would be much more efficient closer to basket.
A player that has actually been really impressive during the pre-season with his hustle and improved play is the unheralded Willie Reed. For a comparison these are Reed's averages:
MPG 23.0
PPG 10.8
RPG 8.0
APG 0.4
FG% 65.6
FT% 50.0
3PT% N/A
BPG 2.0
SPG 0.8
TOV 1.0
FPG 3.0
So let's just hold off before we overrate what Embiid has actually been doing so far.
