because I dont agree that he does. I just dont..
You don't agree with what exactly?
Embiid when healthy is proven to be the biggest impact on your team's record. I think he has the highest ceiling..
None of them have proven anything yet.
I like Simmons because he is a guy that can fit into any system.
How so, when he can't shoot, and isn't particularly effective without the ball? If any player can fit into ANY system it's Porzingis, by a country mile - he's the best off-ball player out of the four, can shoot from anywhere on the floor (off-the-dribble and catch-and-shoot), and can guard multiple positions (his rim protection was near-equal to Gobert's last season).
I think we look at impact as being someone who is a 1st option...he probably never will be that on any contender.
What makes you say this? He's averaging basically 30 ppg at 22, while dealing with more defensive attention than any of those four (on par with Giannis). What makes Simmons and even Giannis closer to being 1st options on contenders when neither of them have Porzingis' shooting ability, and are much more easier to gameplan for - especially Simmons?
Unless Simmons develops a jumpshot, he'll NEVER be a #1 on a contender. NEVER.
Scottie will never be MJ but he fit better with MJ than other players would have that may have been viewed as better players than him all-time..
What in the hell are you even talking about?
Simmons will probably go down in history like other great 2nd/1st options like Wade, Pip, Drex, Pierce, etc....
I am merely answering the question OP presented but answering it from a draft night perspective and not what is going on right now.
