Chris Paul was 16/8 as a rookie with a 45.6% EFG....and shot 43% from the field and 28% from 3.
Vision was certainly better but efficiently scoring, as a small player, takes an adjustment period.
I mean, look at those rookie numbers for Paul. 45.6% EFG is out of the league bad.
If you take that number and look at sub 6'4" players in 2018, just for context, a 45.6% EFG would have ranked 63rd out of 76 qualifying players......right in the area of Jarred Jack and recovering blown achilles Mario Chalmers.
I don't know what Sexton will be but development for shorter players can be slower. CP3 didn't see that star level efficiency jump until he was into his 3rd year, at 22 years old.
I am in no way predicting Sexton will ever be in the same ballpark, just pointing out that even a player as good as Paul needed 2+ seasons, to get a feel for how he could efficiently score as a much shorter PG.
