So, when Michigan Technological University geophysicist Wayne Pennington saw reports about a crack the length
of a football field suddenly appearing in some swamp and woods in the northern area of the state's Upper Peninsula, he assumed it was a small landslide.
Whether it's a guy switching to tight end and
suddenly having to try to block 285 pound defensive ends or it's a guy trying to switch to safety and now having to take on fullbacks on lead plays, the physicality
of most positions on a
football field takes a lot
of getting used to and requires adjustment.
