No. He is very average.
13 trips to the playoffs.
11-12 record.
3 trips to the SB and one win in 13 years, which is close to the average of all playoff teams.
It is thoroughly average any way you slice it.
Perhaps if people were more truthful in their evaluation, it would be received better.
Peyton Manning is the biggest choker ever and sucks in the playoffs is wrong and opens up a valid counterargument.
Peyton Manning becomes mediocre in the post season, and has very average results which are underachieiving compared to his regular season success and eliminate him from consideration as the best QB ever because he may is in the discussion for best regular season QB ever, but no better than average when it matters most is an accurate depiction that prevents the counter argument that he doesn't suck, teams lose games and he didn't choke.
