Pointless facts about the game/series:
Last five games between these teams:
3/3/11: East 2, Grand Rapids 1 (7AA finals)
1/13/11: East 2, Grand Rapids 1
1/14/10: East 5, Grand Rapids 4
1/28/09: East 6, Grand Rapids 2
1/10/08: East 4, Grand Rapids 2
The teams have played 36 times since the 1973-74 season (this is as far back as my records go). East has a 27-8-1 lead in that span. 18 of these games were decided by one goal or less.
They have met seven times in playoff games (East is 6-1), and four of those were section finals (4-0).
After Grand Rapids thumped East 9-1 in the 1974-75 season, they didn't play again for fourteen years. (Hey! Another case where East lost to a team and wouldn't schedule them after that loss

)
The two teams were in different sections from 1974-75 through 1990-91. East went to state once over that period, Rapids went to state ten times, winning three championships.
Since throwing the teams back into the same section in the 1991-92 season, East has gone to state twelve times, winning two championships. Rapids has gone twice, ending second place both times.
Good luck to both teams!
