The turnover is bad luck, sure, but I'm pretty sure he's not going to shoot north of .500. Look at the guy I posted. They are extremely similar (I might even argue my guy is slightly better on offense). Your guy has a 6 pt edge in ath to trade off 14 pts in spd, and 7 pt lp edge while my guy has 20 pt edge in bh. My guy is not even close to shooting .500 with a low distro, and that's with an elite PG dishing it out.
The .690 fg% for the last 2 seasons on my player is clearly inflated by 1 putbacks/tip ins a game. Similarly, Holt's fg% in the past seasons are also inflated for the same reasons.
