Matt Waldman’s RSP Boiler Room: WR Ja’Marr Chase Renting Space In the Heads of DBs


Matt Waldman’s RSP Boiler room examines the speed and acceleration of Ja’Marr Chase and how the LSU receiver used it to rent space in the heads of opposing defensive backs. 

The only thing disappointing about Ja’Marr Chase’s Pro Day is that he only weighed 201 pounds. The rest was a preview of a fireworks show:

  • 4.34-second, 40-Yard Dash
  • 3.99-second, 20 Shuttle
  • 6.96-second, 3-Cone Drill
  • 41-inch, Vertical Leap

This display erased most doubts about Chase’s speed, acceleration, and change-of-direction quickness. Of course, what matters most is whether the player translates his raw material to the field in refined form.

It doesn’t take much to see that Chase does that and more. Chase turns chain-moving targets into breakaway plays and then uses the equity gained from his speed and acceleration to force opponents to guessing games that lead to more production.

These plays against Vanderbilt, including a two-play sequence ending with a touchdown is a perfect example.

Best yet, a percentage of each sale is set aside for a year-end donation to Darkness to Light to combat sexual abuse.
