Terry Roberts took 382 shots last season, by far the most on the team, and nearly 100 more than the next highest shooter, yet he was not nearly the best overall shooter, nor the best 3-point % shooter. The next 3 in shot attempts (Mast, Leons, and Henry) all shot a higher percentage overall compared to Roberts. Plus, other top 3-point volume shooters (Leons, Hickman, Tahvanainen) shot the three at a higher percentage compared to Terry. So the key will be to get more shots from the better percentage shooters.
My point is that whoever among the better shooters takes the extra shots that Terry took last year should see their scoring average rise. Plus, we can expect some added production from Zek, Cody, and Pop, and hopefully a bit from Christian Davis, Darius Hannah, Goanar Biliew, and others. So IMO, it will be a team effort to replace Terry's 14.5 ppg, and it will vary each game.
I also expect the team's defense to be better, and that will also help compensate for Terry's absence. The top 6 scorers in MVC games are gone this year (Green, Mosley, Reeves, Prim, Carter, & Williamson), as well as 7 of the top 10 opponent three point percentage shooters. Those were among the toughest opponents to guard, and hopefully, that will make the defense appear more effective as well.
