Remember the end of "Rudy", where he gets to play, and records a tackle? Well, the same sort of thing happened on Saturday when Rice University put in a running back named Jayson Carter for one play.
And in some ways it's more impressive, because Rudy Ruettiger was 5-foot-6. And Jayson is only 4-foot-9. Rice was up 45-7 in the fourth quarter, so it wasn't actually risky. But he did manage to gain MAYBE a yard.
And when you see the footage of him next to the other players, he looks TINY.
