He also realizes at this point the success or failures of this team this year are going to ride on his shoulders. He clearly looked like a guy trying to make anything happen regardless of circumstance, there was never a thought of not trying to make a play, because the team was playing from behind all night. When you're losing and watching the clock tick away you begin to press and, IMO that's what happened. Ben felt like he had no choice but to make a throw even when a sack or incompletion may have been a better option.
Ben isn't on the decline yet, he's got plenty of football left in him, the team around him has been on the decline for a couple years and we're seeing the fruits of two completely failed drafts, retirement and age.
On a bright note, Polamalu was very, very good again last night, when he's healthy, he's an incredible football player.
