(I'm going to assume you're talking about your NJC team, since your other team's only played 5 games)
Two things come to mind:
1. I don't know what fatigue or minutes settings you're using, but you're playing your starters (esp Gladney and Williams) way too much. Neither of them has a STA to support 30 mpg, and sure enough, they're getting very tired at the end of a lot of your games and shooting poorly as a result. This is also why you're giving up so many second-half leads.
2. On a related note, you're playing uptempo too much. I saw at least three games where you went uptempo vs teams that had better stamina than yours, and two of those were also more talented rosters than yours. That's a situation for normal or even slowdown, but not uptempo.
Overall, I think you were very good defensively, but really struggled on offense, esp in second halves. Part of that was just bad luck - you had a lot of close losses - but part of it was being too aggressive with your starters.
