"I'm not complaining that Smith was effective (I think

), but I'm trying to figure out how he was effective. Was it really just a somewhat easier schedule and SPD?"
Honestly, if you add ath, yeah, I think so.
He had a 25 ath/15 spd advantage in most of his matchups, and is a decent FT shooter. Regardless of anything else, having huge advantages in those areas really makes it much easier to score. Check him out in the games where he didn't have a big ath advantage; he wasn't an efficient scorer.
Honestly, I really think he would have been a huge detriment to the team had his distro remained the same and he played in our conference. He might score 15 or 16, but he's not doing it on 45+% shooting.
On the other hand, you have Dilworth, who has to play against elite SFs every night. I rarely say ths schedule make
this big of a difference, but we had such an elite conference that there were just very few times where anyone could find a true advantage to exploit, which is clearly different from Erskine, who had a huge matchup advantages every night.
