Way too much analysis going on here to the point of nausea....
Alpha, your overall point is actually correct but not necessarily for the statistical reasons you state, many of which are bogus ways to evaluate an individual player and can only be valid if you're discussing a team as a whole, or at least an offensive unit.
Basically , (and look for yourself people) if I'm not mistaken, when Trent plays well , the Bills have won every game in his 2 seasons here. I believe the attempt Chris Brown made was stating that when Trent has an above 80 rating , the Bills haven't lost.
