best D ever? statistically, there is NO WAY, because, due to the offensive evolution that has taken place, it would be darn near impossible to only allow 5 points per game, which was what the '73 D allowed... now, the '96 D only allowed 8.9 points per game, and that SHOULD have been good enough to win a National Title, except the O forgot to show up in game #12, and that is where the '02 squad has it's advantage... at any rate, i can't see the '05 D holding opponents to under 10 PPG-- offenses are simply too sophisticated at this point... now: the '02 D held their opponents to around 13 PPG, which, while statistically is nearly a full TD worse than the '96 D, you have to remember that the '96 O was laying the WOOD to people, throwing up 70 points twice in the first two games-- the D isn't on the field very much when you score on your first TEN possessions, which would indicate that the '96 D, while compiling those impressive numbers, weren't doing nearly as much actual, on-field defending... so i have to conclude that the '02 D, while not statistically as impressive as the '96 squad, was the better overall unit, for the simple fact that when the O didn't show up (Penn State, Purdue) the D won the game seemingly by themselves- IU '96 notwithstanding (i loved it when we tore down their goalpost!)... of course NUUUUUGE and Groomy helped out a LOT... (damn Groom was a good punter- remember that 70 yarder against the Nittany Lions?)
so does the '05 D have a chance to be the best D ever at Ohio State? yes, but only if they manage not only to go undefeated and win a National Championship, but to actually outscore the opponent a time or two when the O is struggling...
i hope that ramble made sense...
