Here are some highlights from our San Francisco 49ers chat, held Thursday:J-weezy-mcbeezy: Give me your best percentage that the 49ers move in the draft to take a top shelf WR?Bill Williamson: 50 percent. Other 50 percent is taking back into the end of first round and grabbing WR and CB in first round.KC from Oakland: Thoughts on Gabbert, Martin, Wright and Bethea moves? Will they sign Cook or another DB before this is over?BW: Gabbert: Why not.
