A foot pound is the amount of energy required to lift a pound by one foot.
Your 2000 foot pound load has enough energy to move a ton upward by one foot.
But why doesn’t it, I hit a 145lb deer with a 450 Marlin load that went in the chest and lodged in her ass, she simply fell down. It didn’t lift her at all?
Sounds like a useless figure for hunting, maybe I will ask Mr. Owl
