Chat about Total Quarterback Rating

Auto Update: Off

Welcome to SportsNation! On Friday, we continue the Year of the Quarterback when we have ESPN's Production Analytics team stopping by to explain the new Total Quarterback Rating developed by the group. The new metric will be officially unveiled Friday at 8 p.m. ET on ESPN.

As the 2011 NFL season is set to start, the Total Quarterback Rating (or Total QBR) attempts to become a more encompassing way of evaluating a quarterback's play and replace the old passer rating which was implemented in 1973. Not surprisingly, Tom Brady, Peyton Manning, Drew Brees and Aaron Rodgers all rank in the elite group of QBs in the new system.

Send your questions now and join the chat Friday at noon ET!
