On the "Play, Coach, Die" diary I posted a few days back (detailing an ESPN interview with Coach Harbaugh), one user suggested that the diary's eponymous catchphrase be made into a T-shirt. So I mocked one up - here is the picture (easily designed at many custom T-shirt sites online).
I think this would be pretty cool, but your mileage may vary.
What I would like to see are mock ups of other T-shirts that people would like to order from our friends at mgoblog/underground printing. So make some mock T-shirts and post them below! And then people can up/down vote each so we can see which these guys should really make, and we can find yet another channel to support our beloved bloggers. Who knows, they might even listen to the masses and make the T-shirt of your dreams.
Funniest T-shirt design wins first prize, which is a hearty handshake from yours truly. Second place: steak knives. Third place: you're fired. Go!
