This was a great season for NU's BkB. But it was nowhere near as momentous as the 1995 FB season.
First, the 2nd round of the NCAAT probably doesn't equate in prestige to the Rose Bowl (especially back in 1995, before the current playoff system).
Most importantly, prior to 1995, the NU's FB team hadn't had a competitive FB season in ages. A 2-win B1G season was usually viewed as semi-decent, for decades before '95. OTOH, NU has been having decent B1G .500-ish seasons for years now (as far back as BC's 2nd and 4th). The NIT is probably equivalent to playing in a minor bowl game, and the NU FB program hadn't been in a bowl game in ages prior to 1995.
In all, the BkB achievement "jump" from previous years to 2017 wasn't as pronounced as the FB "jump" of 1995.
