Canon? Are you kidding me? Didn't you get the 'alternate timeline' refernce?? Canon remains totally in-tact. The original Sulu was a fencer, so that had nothing to do with Picard. I will agree that Chekov was disgraceful, but again, this was pretty much every characters first deployment on a deep space assignment, so the awkwardness works. I think you need to have a re-think, old man.
