The team definitely needs more talent, but you can't do anything about that until the offseason. #1 thing I would change is your starting PG. Brown is sub-30 in BH and Pass and just cannot play point. You need to start Hollen at PG, because he's the only guy remotely capable of it.
Another thing I notice is you have too many people shooting 3s. I would have Kent at 0 for 3pt setting, and Hollen and Velasquez at -1. Everyone else at -2. I would also play slowdown every single game, because depth is not your friend right now. You might also consider running all-0s for your player distro for a few games to see if that helps anything.
I would try this lineup (granted I can't see potential, so I'm not considering long term at all here).
PG-Hollen, Velasquez
SG-Kent, Velasquez
SF-Brown, Romriell
PF-Lee, Dumond
C-Fontenot, Dubois
