It's as much the fact that we don't have receivers, other then Camarillo, who can seperate enough to give Pennington a target. Flacco looked like an all pro because his receivers time and time again got seperation and got open.
I'm surprised this is a conversation, considering you are talking about a qb who had a rating of OVER 100 for 3 STRAIGHT WEEKS! Now he goes up against the #1 defense in the NFL, without quality receivers and we want to bench him. I think that would be the biggest mistake we could make. Henne would get killed and remember up until Flacco played our sorry secondary he had 1 touchdown and 7 interceptions. He was going to sit just like Henne until both of the other qb's got hurt.
We have a quality qb in Pennington, and benching him would just send a message to the rest of the team that the coaches are giving up on the season. We are 2-4, no i don't think we will make any playoff run, but to give up would be a huge mistake. This team is going to have growing pains, they have to LEARN to win, giving up on Pennington would be teaching the team to roll over and accept losing.
