Haha these whacky numbers are some of the highest regarded basketball evaluation metrics available. AG does not play better D, and once again it's not really close (CV has a 4.5 defense +/- while AG has a .8, and CV has a 85.4 DRtg while AG has a 95.4. He is probably our second best defensive player behind Akok. Also he also has the lowest turnover % out of all our guards (including Bouk, BAdams, AG, Gaffney)...
Totally understand that his FG% leaves a lot to be desired, but you can't forget that he is also Top ~10 in the country in FT% and gets to the stripe more than anyone on the team. He's not cut out to be a top guy on a good team (nor should he be expected to be), but he's definitely not the reason we are struggling/losing.
