Field Hockey looks fun, i watched few games on Sportklub, it looks fun
You cant kick a soccer ball, you need 1337 skills to aim the soccer ball... You need to practice few years to learn to aim properly (you can learn to aim within a month, but you can just choose left-right XD ).. And about American Football, i played it once, i mastered the throw from my 2nd time...
Yeah, like I said before. You can easily throw a football like you can easily kick a football. Just because you can throw a football right (and probably not accurate or 'perfect' either, considering not even the greatest of QBs have done perfect passes all the time. It takes real practice, more than a month for sure, to throw against specific team defenses, and you have but a week to study a team's defense (considering its a normal game) and just hope they don't have any tricks up their sleeves.
Also, throwing a football isn't the only thing in the game. Half of the players on the field don't even touch the football and are still as important as every other player.
