I just don't understand why the entire sports world can't hear how utterly stupid the phrase "
he left his feet" sounds.
Suggested replacements (in no order of preference)
1) his feet left the ground/floor/ice/bag
2) he jumped in the air
Anything is better than a phrase that suggests he went somewhere that his feet did not!
I don't know how sportscasters say it (and the vast majority of them do) with a straight face.
