Agreed but not because of his ceiling. Tyrus Thomas had a high ceiling but had no clue how to play the game. Embiid already has shown a feel along with immense potential. I'd be shocked if he were around at 4 (assuming his back checks out). If he was and we took him, it would be interesting to see what DL does with Kanter/Gobert - if anything.
Ok, lets say literal ceiling then. 6'9" 215lbs guy with a high ceiling < 7' 255lbs guy with high ceiling. But I think you know what I meant. TT reaching his full potential is an all-star in a certain era, Embiid reaching his full potential and you're talking super-star/HOF'r.
