We're still just over here enjoying the linemen 40-yard dashes from this morning, because they were a thing of beauty. Outside of the combine, you're just never going to see a linemen get up and go like they do in the 40. It simply doesn't happen: their job is to block, typically within a few yards of the line of scrimmage.
That means linemen can be a little awkward when taking off at a dead sprint. Take, for instance, John Wetzel. I don't know what it is about this GIF, but it makes me so very happy.
And let's be clear: These big fellas are strong and athletic as hell. But these 40-yard dashes? They're a thing of beauty.
