I think Bria can play point late in game, but I think it helps her to start a game off guard.
It's just a matter of aggressiveness. To me, it always seems like when she's playing point, she has the mindset that her job is to set others up, and she's not aggressive at all. Thus, she forces things that aren't there rather than look for her own shot.
When she starts off a game as an off guard, IMO, she's more aggressive, and her role in the game is set by the time Caroline sits down.
Bria's problem though, IMO, goes beyond that. She was an AA last season, and often times was playing the PG position while doing that. Yes, she's going to turn the ball over. But guess what, DT did that quite often too. This season though..she's either mentally frustrated with herself and struggling because of it, or something isn't right physically. I know she looked better the second half but we haven't seen "Big Game Bria" at all this season. And it's concerning.
BTW: I hate to use words like "passionless." I don't think that's quite fair..
