You knew when UW had like two FTs in the 1H what the 2H would look likeand this was classic big ten "we need a premium close game" officiating:
- team gets out to ~15pt lead
- "whoa we can't let this get out of hand"
- asymmetric whistling for 10 minutes, teams don't actually know what's a foul any more
- "ok it's close again, we can maybe relax the whistles for the last 3 minuts"
- hooray we got overtime!
