Pass rushers Elvis Dumervil and Von Miller are carefully counting calories in their hunger to chase down quarterbacks.
Dumervil has already shed at least 10 pounds this offseason, hoping a skinnier version of him will be that much faster on the field.
In contrast, his sack partner for the Denver Broncos keeps trying to bulk up. Miller, the defensive rookie of the year last season, wouldn't mind packing on another 10 pounds or so to help him fend off bigger offensive linemen.
Pound for pound, these bookend rushers may just be blossoming into one of the league's top tandems. They're "Batman and Robin," as Miller has taken to calling them, and combined for 21 sacks in 2011.
