Kick off question

[buffalo_frenchy]

so on a kick off in NCAA after the 10 yards K can catch the ball without touching the ground or a R player.. OK What about the NFL (just curious) because i saw on a one side kick after the restraining line K jump and catch the ball high before R touchs it (or the ground), it seems to be legal. In fact I thought the ball had to touch the ground or a player R and pass the restraining line : i was wrong so. Thank you
