Again, you're in denial of the facts.
Who was a more productive quarterback this season -- Rex Grossman or Peyton Manning? Who was a better running back -- LaDainian Tomlinson or Jamal Lewis? Who was a better pass-rusher -- Shawne Merriman or Karlos Dansby? Who was a better kicker -- Matt Stover or Phil Dawson?
The "results" are in the numbers, just as they are for defensive players in coverage. And the "results" show that Roy was good in coverage this season except with respect to touchdowns allowed.
Without numbers, you don't have any way to quantify "results," and therefore no way to put those results in perspective. So all you're left with is an opinion that's not based on facts or a proper perspective. And those kinds of opinions are worthless.
