Your position has always been determined by who you are capable of guarding. It's the reason that even though Simmons starts at PG for Philly, they play McConnell 25-30 mins a night and to close games until Benjamin learns to shoot a FT or guard someone shorter than 6'5.
He's having trouble separating from guys in Euro, so he's going to need to use his craftiness and size to do that with 2x the athletes and speed of game here. I've watched 2 complete games and chunks of others for him and I havent had the same concerns with his D, but that's because he's always on the court with 4 grown men who are all committed to defense by committee.
He could be a terrible defender of 1's and 2's or he could be solid and hold his own. We wont know until he's over here, unfortunately.
I just want to say that Ben Simmons defence is by far better than his offense despite the how many assists he puts.
He is ranked in the 26% percentile in overall offense
In the 24 percentile in transition offense at 0.93 PPP(terrible)! 31 percentile as a ball handler in transition and that is 75% of his total transition possessions.
He is also in the 47 Percentile as a PnR Ball Handler at only 0.796 PPP.
So these two are his biggest play types by volume and he is putting up terrible efficiency at both.
The Lebron comparisons were premature because Lebron was elite at both from the get go. Unless Ben Simmons develops a shot he is going to struggle even more in the playoffs.
On defence he is in the 68 Percentile allowing 0.876 PPP.
92 Percentile defending spot ups, 72 Percentile against Isolation
For comparison, Lebron our secret tanker is in the 22 Percentile on Defense this season.
He is in the 22 Percentile at defending post ups at 1.128 PPP and in the 24 Percentile defending Isolation at 1.1 PPP
Anyhow, if Simmons is comparable to Doncic in terms of offensive efficiency, then taking Doncic 1st is a major risk because he is definitely going to be worse than Simmons defensively. Simmons without the defence is a minus impact player.
Doncic is going to be as good as his 3pt shot is. I was concerned about his ability to generate good offense in isolation against bigger, more athletic guys, and I was also concerned about his ability to generate good offense when teams decide to take away his PnR ability and switch his PnRs. Right now, he tends to iso a bit too much against teams that take away his passing ability. His explosiveness off the dribble from stand still position is what scares me, and the question mark about his 3pt shot. If his 3pt shot is elite then hillock of explosion in the half court is less of a problem.
