One QB can dink and dunk his way to 120 rating whereas another can be hurling it down filed with pressure in his face all day and not get to 100 but played better.
But this is nothing like that, nothing at all.
We have no stats on AD being out injured so how on earth can you say what another player would have done.
The margin for error on the QB rating is fairly high but relatively easy to factor in different elements.
With WAR, you cannot factor in all the permutations. Not only are there too many, but many of them cannot be measured.
I'd be staggreed if teams took any notice of this whatsoever.
I'd put my money on that steaming pile of poo, the law of attraction, before I'd give any credence to this.
There is nothing either good or bad, but thinking makes it so.
