That's the thing it may look like the B10 has tough defenses but partially that's because they don't face offenses like you might see in the B12. It's part of why I've always stuck by the most games are potentially winnable for us outside of OSU (and maybe Michigan), despite how poorly we look on offense. The B12 may look like they have lousy defenses but that's partially because they face fast moving productive offenses often unlike the B10. OSU and maybe a little Purdue and Maryland (both inconsistent) and that's about it. Even the SEC supposed defensive conference have had a bunch of productive offenses now from UGA,Alabama to Tenn, Ole Miss, Miss St, Ark, LSU etc..LSU's champ season was on the back of historic offense. Tenn's performance this year is on the back of highly productive offense.
That's why I give you the examples of supposed top defenses and how when they play strong offenses they get dragged into shootouts instead of rock fights. It's an uncommon defense that can hold down really top offenses, like say UGA's last year. Alabama's defense was #2 in the country they said in the game, I thought it #6 but whatever, and they lost 52-49....in regulation lol. Dantonio's MSU against Briles' Baylor...game was in the 40s. Riley's OU vs Smart's UGA and game was 40s and 50s.
Offense is the way to compete for a school like us, not rock fights. It's no guarantee it's just the avenue with the most potential. I've said it before, it could fail and I would still try again and again because that's what I see across the landscape. Illinois is winning with top defense and solid offense but for every one of those, you'll see a WF or TCU or Coastal or Pitt or Tenn performing above their station on the landscape with strong offense. If you have a strong offense with a mediocre defense, you have a decent shot of making some noise.
