I received an Email from a Spartan fan of mine ranting about how he's sick of hearing about the officials and how he heard from someone else this week that the officials from Monday's game had Big East affiliation.
I decided to look into it further (statsheet.com):
The refs who worked Monday night's game (Tony Greene, John Cahill, John Higgins) have done 3,500+ games since 1997
- 559 were Big East games (16%)
- 72 were Big Ten games (2%)
- This season neither Greene or Cahill worked a UM game, they collectively worked 14 UL games
- Since 1997, Cahill & Greene have done 52 UL games, and only 6 UM games (Greene had never officiated UM prior to Monday night).
