| When pass blocking,
the main objective
for any offensive lineman is to resist any external force with as
little disturbance to his initial position as he can possibly manage.
He has two physical principals with which to help him accomplish this
goal. An offensive lineman understands even without physics that
the more mass he has, the harder he is to move. The concepts of
momentum and inertia prove this to be true. |
| An
offensive lineman also looks to counteract external forces by lowering
his center of gravity as close as he can to the ground so as to reduce
the amount of torque a defender can place upon him. By squatting, a
lineman effectively shortens the length of his moment arm from
his pivot point ( in this case, his feet ). It is often touted
about the NFL that the low man wins, a little rudimentary physics helps
us understand why that is. |
