Yes, we do need a better quarterback. But guess what? So does do about 28 other teams. There's only a handful of truly great qbs(Rodgers, Brady, Roethlisberger, Brees). Yep, Alex wasn't making plays. But neither was the O line or any of the wide receivers besides Crabtree and Williams(who needs to be the #2 right now). Delanie and Vernon were also non-factors and the playcalling looked like Jimmy Raye Jr was back.
btw those pictures clearly show those receivers with defenders around them and pressure in Alex's face so I don't know why they used that image to prove anything.
