We're not looking at careers. They are playing the game this season. So yes, there are two killer QB's. I consider a guy to be a killer QB who set the NFL RECORD for completion % in a season this season and led the NFL in passer rating and TD's this season. I'll state that without a doubt I believe Manning is the best QB who ever played in the NFL. However, if you are talking about killer QB's right now, then Brees is in that discussion.
