Seth's a pretty poor option as PG, IMO. But he may be what we have to go with if Peters either isn't 100% to start the year or just isn't ready quite yet. Or if he's more of a combo guard like Seth himself, as I've seen suggested.
I think Seth is a good player, he's just not a point guard. He can't break a press by himself and he isn't great at initiating any sort of a set offense. He can get to the rim off the dribble and he's very quick, so he's definitely the best option right now, but I'd really like to find an actual point guard and let our players play to their strengths.
