Rex Ryan may be a lot of things: A U.S. Soccer fan; a hot-tempered headset tosser; or a cross-dressing Browns fan. Great defensive mind must be at the top of that list. His deviously inventive coverage and pressure schemes frustrate offenses by confusing the quarterback’s reads. The Jets mix up their pre-snap looks to maximize confusion, and they shift and camouflage very well.
Look no further than these early plays from the Jets’ game against the Green Bay Packers for confirmation. These are the various looks Ryan threw at Aaron Rodgers and the Green Bay offense on their first full series (discounting the aborted first series that Rodgers fumbled away on the handoff) to slow the Green Bay passing game.
