Very true, I wouldn't say it's one particular style of offense that works persay. The key to me IRT what works against Bama is pretty simple (in theory, harder to do in reality) -- be aggressive, protect your QB [especially from their blitzes, which come essentially every 3rd and medium-to-long in Kirby Smart's defense], and find mismatches when possible; especially in pairing up your WRs against their LBs in pass coverage (they, a lot like OSU this year actually, like to stick to packages that are LB-heavy rather than introducing extra DBs). The key to Bama's defense is shutting out your running game first, which means a lot of leaving their DBs on an island. Doesn't always hurt them because their secondary is very talented, especially Landon Collins at Safety, and because their pass rush has been very good this year. However, if you CAN protect against their pass rush, that's when you start to see a lot of those long passes being completed that have been mentioned. The key is to keep your QB upright long enough for the WRs to be able to run those long routes in the first place.
Alabama's pass defense is #58 in the country, that is not on par with what they have been in years past. What that says to me is that there's a weakness to be exploited. Key is whether OSU can give Cardale the protection he needs to make those throws, and whether the OSU WRs can win their one-on-one matchups. They have been lately, let's just hope it continues!
