The reason that the majority of NFL talking heads, prognosticators, bloggers, experts and fans alike think that Aaron Rodgers is a better football player than Brett Favre is simple.
Perception is reality. They still see Rodgers, while Favre, having retired in 2010, fades under the tide of NFL history.
They are also susceptible to delusion.
What they remember is Rodgers in a stunning week one win in Lambeau against Chicago (when in the final minutes the Bears decided not to cover Randall Cobb) and not the week 13 loss to the 2-9 Arizona Cardinals in the same location.
