He's also playing with better players. Makes a difference if the guy across from you is Hayward and not Ingles.
Exum started 4 consecutive losses vs Chicago, Houston, Memphis, Denver. Quality teams, the last 2 better than their record.
In 5 of the 6 games he started(wins vs Miami and Orlando the other 2) the team 3P% was between 20 and 30%. The lossn vs Houston was the lone exception with 44%.
A player reliant on attacking, coming back from an ACL tear in his 2nd year at age 21 is supposed to be efficient when the whole team has an off night from behind the arc and makes it easy for the opponent to pack the paint with bodies.
Not a big coincidence, that his +- takes a huge dive.
I'd still want to play my 21 year old developing player with good instincts and habits over a 26 yr old in his prime with shaky habits, who can barely achieve the same advanced stats against weaker competition, in almost any circumstance. I understand that Quin wants to instill some stuff, but please do it when our schedule actually allows Exum to put in extra effort into practice and make a case for himself to reenter the rotation.
Regardless I'm not that concerned, Exum's most likely not going to move the needle in this year's playoffs. It's about regaining trust in his knee, developing certain aspects. The time frame that's most crucial for him is going to be next offseason, where he'll have to add/solidify key skills and next season where it's showtime for his next contract and he'll have to break out.
