what are the main pros, to salary caps

To prevent monopoly, make it more fun for everyone and lets more teams have a chance.

if you want more than that just google it man.

yankees are good reason why baseball (im not sure if they have one) but its seriously fucked if they do lol.

the main 1 is equality.
if theres a drafting system it ruins that though.

Even playing field

Having a salary cap doesn't mean that there will be an equality amongst players. Some will get paid the maximum while others will get the minimum.

equality amoungst teams u dumbshit.

yea dumbshit

They also create a minimum that each team must spend so there is a guarantee that if all teams meet that minimum that player salaries will be at a certain amount...
