OK, I am confused by Giddens name being on the poll. He makes Tony Allen look like Chris Paul. But ultimately, no, we do not NEED another PG. I think it would be nice to sign one for depth, but I don't think it is necessary.
I would say though, that it will likely be Hudson OR another PG, not Hudson AND another PG. If he is signed, they will likely keep him as the emergency PG...at least until February, when they may look to upgrade if they can.
