Most 270 lb plus linemen have no wheels to speak of; DUMB ASS.
Most elite linemen have extremely explosive speed over very short distances. You'd know that if you ever played a real sport, dumbass.
You're an idiot. First off you, stated starting at 10 yards (and beyond). Second off, no they're still not that fast. They often have a quick enough first step. But they play their position cos they can bang. A great many of them have guts hanging out. But most the time, an average speed quarterback evades them. If you're going to act the expert, don't give me SANCTIMONIOUS BULL SHIT. It only makes you look like a total fool.
