Damon Sheehy-Guiseppi is the best feel good story from the NFL preseason and it's not even close. Sheehy was sleeping outside of 24 hour gyms a few months ago when he crashed a tryout in Miami. During that tryout he ran a 4.38 40 yard dash.

The Cleveland Browns gave him a tryout.

In the first preseason game, he scored an 86 yard touchdown on a punt return. Sometimes it doesn't get much better than that.
