What do you mean by "skill" exactly?I don't think Drew is what he used to be in terms of skill and arm strength, and his stats bear that as does watching old highlights from the 2009-2013 seasons. I like to refer to him these days as a very elite game manager that can show flashes of his former greatness every once in awhile; his game is more predicated on efficiency than ever before, and his TD to INT ratios as of late are representative of that.
However, with that being said, to rank him #16 is absolutely ludicrous. There is no way you can tell me that there are 15 better quarterbacks in the NFL than Drew Brees. No freaking way.
