This year St. John's was 245th in 3-point shooting at 32%. CMA's style generates extra shots over the opposition, which somewhat mitigates poorer shooting, but it's obviously a goal to increase this percentage. For reference, 35% puts us in the top 100 and would equal about 2 extra points per game. It would also open up the floor for drives, etc.
Does it look like this will improve next year?
We're losing heron who was the best 3 shooter on the team. And LJ, who was second best may leave as well. A few of the core guys were looking decent as the season wore on. Williams got hot, and seems like he could be a 35+% guy. Both champagnie and earlington seem like 30-35% guys, but with lower volume than williams. Also if posh (or mcgriff) take on more of the PG role, playing dunn off the ball more will likely help him as he'll be able to take fewer desperation threes and also have his feet set when he does take them.
For the guys coming in: Cole's stats show him hitting at a 44% clip at juco, so seems like he could shoot in the 35+% range. What can we expect for posh and Wusu? Stats on rumble in the garden from last season suggest that Posh shoots in the 20s from deep and Wusu was hitting at around 34%, but I don't know what they've done this season. May also be another player or two coming in.
From what we currently know it looks like it will be tough to replace both LJ and Heron, although the addition of Cole and Williams' emergence at the end of last season suggest that it's possible to really improve here, particularly if LJ sticks around. I'd also expect that LJ may be able to push his % up toward 40 if he stuck around, because he was really harmed this year when Heron went down and he became the focal point -- the new additions will take some of that pressure off.
