Yes, I do believe that it COULD look different ..... however, that said ... A LOT also depends on our personnel. When we have the personnel to play press coverage and more multi-DB looks ... we ALMOST ALWAYS use it against "pass-first" teams.
We've come out against Purdue before in press coverage ... and spanked them. However, we don't always have big, physical CBs like Fletcher or Godfrey.
In '08 and '09, in some respects, we had more experience in the secondary (apart from Sash being a newbie in '08) ... and it reflected in how pass-first teams fared against us.
Specifically, in '09, Northwestern musted a TOTAL of 239 yards against the Iowa D. That's TOTAL yardage. Kafka was one heck of a QB and managed to pass for 500+ yards against Auburn in a single game AND 350+ yards against Wisky in a single game. While, admittedly, he was injured when playing against Iowa ... Northwestern's pretty formidable O ended up doing NOTHING all day!
In '08, the Northwestern O admittedly mustered around 390 yards of total O ... roughly 280 of those yards being through the air. However, a few factors are pretty critical in that game. First off, Northwestern's O wouldn't have had the ball for near as much time as that had the Hawks not "gifted" the Wildcats 5 turnovers! Furthermore, A LOT of Northwestern's yardage resulted from poor tackling. Both Lane and Peterman made big plays at the start of the 2nd half ... both being the result of missed tackles. Northwestern's success in that game was MORE a result of the Iowa D making uncharacteristic mistakes.
