If your default is the team has no flaws that is not reality. Not sure why you're taking this position doll. Do you really want to make that argument?
You didn't ask me, but let me just point to one example of your using "garbagey" "facts" to support an opinion. You say 54% of Cobb's yards came after contact as an argument to support your claim that the offensive line was not very good. That sounds like and interesting fact, but if you examine it, it's meaningless. There's no frame of reference. Is 54% yac exceptional? How did other backs compare. Does Cobb gaining 46% of his yards while being untouched reflect at all on his offensive line? How is contact defined? If a would be tackler got a hand on Cobb's ankle while being pancaked by an offensive lineman and Cobb shook loose for 50 yards more, is that considered yards after contact? And if so, shouldn't the line get just a bit of credit for that yac?
If it was me, I'd just say that Cobb had a very impressive year, ran very hard, broke a lot of tackles and benefitted from a decent offensive line. A nice team effort. I'd just leave it at that.
