The guy explained it and it was a valid point. He basically said that no specific metric is a perfect identifier of how good a defense is. The flaw in Points Allowed is that it encompasses points given up by offensive turnovers as well as run-backs on special teams. The flaw in Yards Allowed is that it doesn't measure the stat most directly related to wins, points.
I thought they had a good discussion.
I don't get some people here bashing the discussions on this site, though. Look at the KU thread - there are rational, well-thought-out posts and a couple of nonsense posts. Holding that up as some paragon of message boards while comparing them to this board... not getting it.
I sometimes wonder why some people are members here when they clearly do not respect the other members. Doesn't make a lot of sense.
But the bottom line is the Defense that keeps the other team from scoring wins. The yards against is just stats (fluff) in my opinion.
but obviously our offense didnt help matters. they're inability to stay on the field forced our defense to stay on the field much more than the other great defenses.

as you can see our defense was on the field more than 100 plays more than bama and florida, and with all that extra time on the field, of course we'll give up more yards. but the impressive thing is that we only trail texas in yards/play, and you would think that fatigue would eventually set in and they would start to break down, but that never happened all season, thats what was most impressive IMO. I honestly think we were really lucky to have our defense to fall back on with our struggling offense. if we had the defense of 2008, i wouldnt have been surprised if we wouldnt have have become bowl eligible. but thats just my two cents, but this is why i truly do appreciate what this staff has done in only two short years, and that is why I am excited for next year.
