As much as MT fans complain about "little middle," playing the spring game on a soccer field screams little middle/OVC. Pretty sure attendance was down last year due to the smaller capacity of the soccer stadium. While I don't need a true game as a previous poster mentioned, it sure would make it more enjoyable. Heck I'd pay $20 to go watch the coaches draft the teams if they did it that way.
Looked back to 2009 on GBR.com for spring game attendance numbers, here's what I found. I'm going to assume the years it wasn't announced is because it wasn't that great.
2014 - not announced
2013 - 5,000
2012 - 4,214 (I remember being shocked at how many people were here coming off of the 2-10 year)
2011 - not announced
2010 - 3,110
2009 - not announced
