hockey, this is no-brainer

Between those 4? Hockey for sure

Billiards.

Cricket is one international sport that actually looks pretty interesting to me, not only as a spectator, but as a participant.

i'd have to say curling

Out of this list, I'll have to say Basketball.

ONLY because of the large amount of players trying to make it, the teams are limited and the number of player per is smaller than any other team sport. HOWEVER, it is nowhere close to the most physically demanding or difficult to play.

Golf would get my vote on a normal list, ainec. The difficulty to play golf at a pro level consistently is by far the most difficult of all sports.

Hockey would get my vote, but when you say "Professionally" I don't take it as NHL only. There are pro leagues all over the world.

Hockey, then baseball, then basketball, then football.

Hockey and it's not even close.

Football. THey don't take a week off for no reason. Rofl

I think tennis and golf the gap between amateurs and pro's is the highest but that's just one mans opinion
