Well you certainly did not see Joe Looney out there did you?....... Plus how quickly the 49ers forget Chilo Rachal. One bad Guard can tank your team. Looney often mentioned as an eventual replacement for Iupati if he leaves in FA. "He will play just as good as Iupati." Seen this quote on the WZ. Really. He is filling in for an absent Alex Boone right now. But he is often said to be a replacement at either side if we lose Boone or Iupati in FA.
Obviously Looney is not a replacement for either one of those. He got tossed around like a rag doll. He could not hold the point of attack. There was no running room on his side. Lots of running room on Iupati's side. He's not as good. Guard does matter. It's not as unimportant as made out to be on here. You can't just plug in anybody and get the same results.
