At the risk of starting another irrational Brady-Manning argument... This is an interesting post by Neil Paine over at Chase Stuart's site, looking at which quarterbacks have won more or less in the playoffs than what you would expect based on the Vegas line. It's great to call it the Manning Index because it has a Manning at the top and a Manning at the bottom. Also interesting is that Tom Brady isn't the only veteran quarterback who had a lot of playoff success early, and very little later in his career. He has this in common with Brett Favre, Troy Aikman, and a guy you probably don't think about much, Dave Krieg. Krieg took a 9-7 wild card team to the AFC Championship game in 1983 and went 1-1 in the playoffs in 1984, then was 0-4 as a playoff starter the rest of his career.
