I see it a little differently. I think there's been several playoff games the Bison have won over the last few years there that were only a few plays away from turning out like the JMU in '16 game did. Off the top of my head:
SHSU (natty) in '11
Wofford in '12
GSU in '12
In '13.... ummm ok got nothing there.
SDSU in '14
CCU in '14
ISUr (natty) in '14
UNI in '15
What seemed to bail the Bison out of those games was either one unit played heroicly (defense in '11 SHSU and '12 Wofford, offense in all 3 of those '14 games, or special teams in '15 UNI) and/or the Bison had a special kid or three that made incredible plays (Grant Olson's 198 tackles against Wofford in '12, the Wentz/Legendowski connections against SDSU and ISUr in '14, Jensen's refusal to lose against GSU in '12, etc). In all those games the opponent had the horses to beat the Bison if their kids had stepped up the way those Bison players did.
They just didn't have that happen for them against JMU last year. That game, like the games I mentioned above, was a play or two during that crucial 2nd half stretch where it was tied up from the final score being flipped. I don't think JMU had an epiphany or was any better strategically than numerous other playoff opponents that the Bison have beaten over the last 6 years, they just had kids who made heroic plays (like Schor's 3rd and long strike for the TD that put them up 10) and a defensive unit, specially along the defensive front, that played heroically against the NDSU power run game.
Call me a homer or a rube but I'll gladly take the guys in green and yellow this year over anyone else in the country. One playoff loss where they didn't make the plays doesn't erase the last 22 playoff wins where they did. Sometimes it happens but I'll be more than happy to see another 5 titles before it happens again sometime in 2022.
