First of all, who gives a rats ass about NFL Networks player rankings. Notable "Top 100 Players" from 2012.
#20 = Vick
#17 = Julius Peppers
#6 = Big Ben
They all went on to have horrible 2012 seasons.
With that said....81 is pretty good considering he started only half of a year. Honestly, I would have been happier if he didn't even make the list. I would rather be under-hyped than over-hyped.
As Harbaugh would say about people showering you with praise....'Kick 'em on the shins and get back to work'.
