Here are some highlights from our San Francisco 49ers chat, held Thursday:Mike from Chico, CA: I have heard several people say the first need we need to shore up in the draft is backup QB. Wouldn't it be a waste of a top 3 round pick on a QB that will sit there for 5-6 years? I would assume there would be better options floating around FA in the summer.Bill Williamson: I'm not sure they use a top-three round pick. But with a surplus of picks you never know.
