Sorry, I think he is 100% correct here when he said this:
The Joey King moment is when a ridiculed, winless in the BIG, no expectations team somehow beats a heavily favored team.
I'll add that it was also about the joy of fans who had waited a long time for a first conference victory. That team lost its first 13 conference games so the fans had to wait considerably longer for their first conference win that year. It wasn't about "wait and see this team next season." Yes, the 2016-17 team was the best in recent history but a big part of that was four players (Coffey, Lynch, Springs, and Curry) who didn't play on the 2015-16 team.
The 2015-16 team won only one more conference game (the next one) against hapless Rutgers (the last team to win only 1 Big Ten game in a season). After that, it fell apart with suspensions and at least one injury.
