Shawne Merriman weighs 272 pounds.
This is six pounds less than Anthony Muñoz, probably the most dominating left tackle of all time. Shawne Merriman also runs the 40-yard dash in 4.61 seconds. When Jerry Rice attended the NFL draft combine in 1985, he reportedly ran a 4.60; Rice would go on to gain more than 23,000 all-purpose yards while scoring 207 career touchdowns.
You do not need Mel Kiper's hard drive to deduce what these numbers mean: As an outside linebacker, Shawne Merriman is almost as big as the best offensive tackle who ever played and almost as fast as the best wide receiver who ever played. He is a rhinoceros who moves like a deer. Common sense suggests this combination should not be possible. It isn't.
