Your best estimate, has large, lucrative, salaries helped, hurt, or had little effect on professional sports?

Imagine some hot shot athlete signs with whatever team to play five years at 75 million dollars with a 30 million guarantee, or some other similar arraignment, do you think large deals like that have hurt, help, or had no effect on pro sports? This is the industry as a whole not looking towards the individual who got the deal. If any sports were effected, which ones do you believe were by your best estimate and how, for good, bad, or other?
