I'm in the same league as Coach of the Year, and I can tell you that 13-14 IS is not needed for that level of shooting. My bigs are all in the range of 4-8 JS and 7-9 IS, and are shooting 46-54%. Rather I think it's likely that the use of RnG, along with poor stamina, and passing, is leading Singletary to take many poor shots.
