When the Seahawks consider which offensive linemen to draft, the broad jump is the single most important test they consider.
Allow me to present the evidence.
Before we start, here’s how BodyBuilding.com describes the test and how it compares to the vertical jump:
“The broad jump expresses horizontal power, which is more specific to football motions than vertical power. Vertical power helps you go up for a ball, bat down passes or hurdle defenders; horizontal power helps you cover the full 5300 square yards of the ironed grid. A pure acceleration step expresses horizontal power.
