New Research: 50% of Bear Front Pressures Create Unblocked Rushers—Here's How: 5-Up (or Bear) presentations place maximum stress on offensive lines by forcing them to identify, sort and block rushers in mere seconds before havoc strikes the quarterback. X&O Labs analyzed over 2,400 instances of these Bear presentations at the FBS level and discovered that 50.56% of quick pressures involved an unblocked rusher in these schemes. Their research also uncovered the quickest "time to pressure" patterns against each Center protection decision: stay home, slide to field, or slide away from the back. X&O Labs’ full study includes which positions generate fastest pressure, plus complete analysis of unblocked pressure rates from both 5-Man and 4-Man rushes in Bear fronts. You'll be surprised what their research revealed about exploiting these protections—See the full study, game film and coaching points here.
