Cool stats bro. Reason why these are fun stats to cherry pick.
1. Welch took 7 shots a game, 3 from 3. Welch shot 43% from 3 as we all know. but also as we all know, he got most of these looks WIDE OPEN due to guys like Williams, Mbakwe (in his few games), Sampson, and later in the season Dre drawing the primary defensive attention. When you're the tertiary or quarternary offensive option, you are open more often from deep. Kudos for him in hitting those shots, but to reference, Austin Hollins was a 37% 3Pt shooter from distance that year compared to 30% this year. Being open helps.
2. Who on this team do you have to feed the ball at the rim on this team? Welch had Mbakwe (again limited), Williams, and Sampson to feed the ball in the post to as well as solid shooters that season at least, probably due to the higher attention necessary down low, in Dre, Austin, and Armelin. Those inflate assist numbers when you're the guy with the ball in your hands. Just ask the guy from Davidson who got to fire the ball to an open Curry all year (not comparing the 2 directly, but open shooters sure as hell help).
3. Welch wasn't asked to create his own shot. Welch took 4 shots inside the arc/game that season. Little Dre is asked to penetrate and kick and score himself. He is the focus of our offense, much of which is in the paint, as is evidenced by his 8.5 shots/game with only 1 from deep. Those differences in what is asked of the player is going to lead to drastically different numbers in terms of "efficiency". Also movement in the paint leads to more turnovers. how many bounce passes in the paint have gone off our guys hands and out of bounds to count as TO's on Dre? Or guys not sealing correctly on post entries? good plenty including several last night. you don't see stuff like that when you are perimeter passing to 3 point shooters.
Trust your eyes. Dre is a "better" player for us in terms of that he is the guy making this team go. With Welch that season, we didn't lose anything going to different guys in his spot. Look at what happened when we switched to letting Dre Hollins handle the ball more and more.
