2021 Spring Playoffs Wasn't rooting either way, and both teams qualify for this distinction, but it's always good (as an independent viewer) seeing a team finally get over the hump. Sam Houston had become known for not just losing in the playoffs, but getting blasted when they lost.
39-13 in 2012 to NDST
35-3 in 2014 to NDST
62-10 in 2015 to Jacksonville State
65-7 in 2016 to James Madison
55-13 in 2017 to NDST
Three of those were semifinals and a fourth was the title game so this wasn't some crap team that snuck in, won a game and faced the 1 seed.
Related note, over the past decade, Sam Houston has made the playoffs 8 times. Of the 7 times they didn't win the title, four of those they lost to NDST. SDST has made the playoffs the last 9 seasons. Four of those times they were eliminated by NDST. It makes sense considering NDST has won 8 of the last 10 so if you make the playoffs every year, you're going to lose to NDST a few time. Still crazy to see though.
