at one point i maintained the NT win streak lists but its been so many years, maybe one of these days i'll resurrect that. wouldn't address regular season wins though. i agree that lostmyth had back to back 35-0 seasons, but i don't know where.
that 16 straight conversions of title games is a pretty crazy stat, i can't imagine anyone has that beat. considering how many programs piman runs, that is sort of amazing. i could see it with 1 or 2 programs perhaps, with an intense focus, but not across a whole boatload of them. that's crazy!
i don't know how one could categorize it, but i sort of always felt the thing i've done that was least likely to be reproduced was how quickly i had d1 dominance under my belt. i got to d1 not very quickly, i took my time in d3, i think it was 6-8 seasons. but still, i got there as still a rookie - i had picked up other teams by then, like a few, so i might have had been close to 20 seasons already, but i am pretty sure i was still sweet 16-less (the s16 was an initial wall for me).
like everyone, my intro to d1 recruiting was an unmitigated disaster. but after 4 seasons at a mid major i picked up on a d+ (i think), and then 2 on a C prestige BCS, i won 5 titles in 9 seasons. so my first 15 lifetime d1 seasons had 5 titles, starting on a d+. i could see like, a d2 super coach jumping straight to a solid BCS program and winning 5 in 15 seasons, but even that i find pretty unlikely. this was also back in the days when high d1 teams / conferences were insanely advantaged in recruiting, but also worlds were full and competitive - only once before had a coach ever won 5 d1 titles in 10 seasons, and that was when tark was brand spanking new (by oldresorter), which is a bit of an edge case. just to win that 1st title on C recruited players was considered a minor miracle. i definitely consider that my #1 accomplishment, and least likely to be matched, even though the bar for doing so is so much lower now. dogg - its someone like you who could put that 5 titles in 15 d1 seasons to the test!
