For the record, I like PT and think he adds value to the team.
I would like to remind you all of a guy named Fred McAfee who took over for an injured Dalton Hilliard, Gil Fenerty and Ironhead during the 1991 run to the NFC West division title. He finished the season as the teams leading rusher averaging 4.5 yards per carry. He did not have the great one game performance that PT did against the Bears but he was a very solid RB for a stretch of games in a division title season. Fred's career stats continued to declien from there until he became a career special teams player.
Many here want to hang the hopes of our running game on PT after one great game. Why? What do you have to prove he will be any different than Fred McAfee?
