I've only attended one or two spring games, but maybe I've watched 10 of them on tv. It's enough of a bummer when the scrimmage part is cancelled (i.e., just a practice), but cancelling the whole thing is significantly more crummy. Michigan has a couple experiences with this during my time. RR's first year he almost did that. The stadium was being renovated, so there was a good explanation, but the backlash was so severe, they moved it to a local high school instead. I think it was before the 2016 season that we faced something similar (new turf or something) and moved it to Ford Field in Detroit. And then last year the whole thing was actually cancelled due to weather. All of those sucked to varying degrees, with last year being the worst and the Ford Field year being least bad (it was a full scrimmage, it was televised).
