Yeah, Early makes no sense whatsoever to me, either. Way out of the way for both teams. Granted, the size matches the historical median and has been used for playoffs before, but there are better choices that aren't so far out of the way. I guess the draw is that its relatively new (circa 2008)?
Tuscola is probably the optimal site - dead center between WV/Trock, capacity of 3500 (right near the historical median of 3000 for quarterfinals), and has been used for multiple 6-man playoff games in the past.
However, I'm with you, I'd rather see the game at Trent. It's also right in between both teams, new facilities (inc locker rooms), nice field, and designed for 6M.
