going from very poor play to about average on the right side wasn't an upgrade? Going from Williams to what they have is not an upgrade. Those short term grades mean very little, especially on an offensive line, which is a unit of 5 players all depending on 4 other teammates for how well his play looks. The fact remains they have one guy, Williams, who is even close to an ideal player for his position. They are old and incredibly shaky at every other spot. And Williams history still leaves him as somewhat questionable. I'll grant you the point about the sample size and even acknowledged as much, but considering the actual circumstances, it's not a big leap to make that Williams would have a hard time on the right side. He was being asked to play the opposite side to what he had played all his life... I believe he only played on the left side (tackle and some guard), and being asked to do everything in reverse can't be easy. When the offensive line really sucked, Williams's play at RT was probably a big contributor (along with, obviously, Pace's horrid play). I can't really argue against being skeptical about it, but all I'm attempting to do is make a case for why the line played better down the stretch (which it did), and why that improved play might not have been a fluke.
