The entire article is pretty flawed because his totals all seem fairly subjective. For example, in his intangibles ranking, Peyton is #1, followed by Wilson at #2. But it's based on absolutely nothing except him saying leadership and competitiveness are tangible, followed by no results. And whatever statistics he does use are flawed: for example, he uses sacks to measure pocket awareness but doesn't adjust it for how many dropbacks a player had. Just a pretty terrible execution of "analysis" in his article.
I do think Brady had a "bad season" by his standards but to say he's the last QB out of the 8 in the playoffs that you'd want is very extreme. He still brings so much more to an offense than those 3 young NFC QBs who are basically running QBs or 1 read QBs (i.e. not going through their progressions).
