I saw Limus Sweed, former UT receiver, drop this ball yesterday. The fact he screwed up made the clip fairly noteworthy, but the icing on the cake was what came afterwards. It was the ol' "I Just Messed Up So I Better Act Hurt" routine. But, man, it got him no sympathy from the home crowd. When he finally walked off the field so slowly (to show he was really hurt), he was booed mercilessly.
I remember a guy at Bridgeport who would do the same thing. If he ever fumbled you could bet the house he'd be rolling on the ground holding his knee or arm. It was a sure thing.
