I really do not think the team should tank the season... it is only week 12, that is a mentality that is ok for fans to have but not players. Sitting Eli really does not accomplish much, let him play with his young WRs no reason to have them work with David Carr who in all likelihood will be starting for a different team next season.
Fire the fuck out of the coordinators, replace them with interim guys already on the staff and tell TC it has been a great run, but he retires after the season is over. A new Head Coach (Bill Cowher) needs to come in with his selected assistants and they need to turn this team back into the power football team that has made it great across it's entire history. First thing, is NEVER line up in the Shotgun for a running play on 2nd and long... NEVER AGAIN!
