Nuances based on "toughest to defend"?! How do you defend someone that wins 5 Super Bowls while never having a dominant position group. Wins as basically a rookie, has Moss & doesn't win, very good but no elite defense ala Chicago Bears or Baltimore Ravens, wins without his go to HOF TE. Man, those years with Peyton have really rubbed off. Bitter dude IMO & I still like him.
