As we've all learned: there are lies, damn lies, and statistics - which are for losers.
The neat thing about stats is that you can pick your side of an issue and then find, create, or tweak statistics to support your argument. Stats still don't win games or OU would be undefeated.
Murray has good stats, I've not seen anyone here argue against that. Tua has good stats, the Alabama defense has good stats, the Oklahoma defense has bad... issues.
Earlier in the thread a sooner touted the OU defense as being better, statistically, than 5 defenses we've played. I find this claim amazing/puzzling - considering we've played 13 games - as simple math, that even Alabama grads can do (but someone might want to check me) - means we've played 8 defenses better than Oklahoma's. I doubt it takes much research to find the answer to this question but I'll ask it (rhetorically) anyway: how many defenses has OU played that are better than Alabama's? The answer certainly won't be 8, or even 5.
