You know, something uplifting, in some 'MgoBlog Supports You' kinda way. I would go with,
It's been a rough stretch. The team has been bruised and bloodied, perhaps a bit discouraged, but know this: The entire Michigan community has faith in you! We are proud of you and will support you through thick and think. The team has had it's share of growing pains, and more than it's share of bad breaks, but we know that you will not give up and come next Saturday the team will give its all against Purdue. Be steady in your resolve, be disciplined in your assignments, be confident in your abilities, and you will be singing 'The Victors' after the game!
