Warrior General Games

What are these stats??

KL
PNKD
REVPNK

Please help me understand this strange language.

KL = Knocked Loose (when a receiver makes a catch and then has the ball jarred loose before he gains actual possession)
PNKD = Pancaked (when a defensive player is knocked on their butt by an offensive player)
REVPNK = Reverse Pancake (when a defensive player knocks an offensive player on their butt)

Thanks!
