And also, players often give up plenty when entering the portal. Many don't get an offer and drop out of college. Others give up exposure. Some end up losing credits. Some get a lower quality education.Other job markets aren't always fully free for movement. If Somebody wants to hire Me for a key position, They may want to have me sign a written contract hiring Me for a specified period of time with a specified Compensation Package, That Contract will contain two items to benefit the Employer. A non compete clause, preventing Me from working for a Competitor for a specified period of time in a specified Geographic area. Second, a Non-Disclosure Agreement preventing Me from sharing Confidential information with a new Employer including client lists.
So the bottom line is I decided I want the certainty of Employment for a period of time at a specified Compensation package with a buyout if the Employer terminates Me before the term of the contract expires. But to obtain that benefit, I negotiated away my Freedom of Movement to new Employment or accepted restrictions to it.
In the Transfer Portal, the Player gives up nothing in terms of limiting freedom of movement.
Okay, they haven't been giving up freedom of movement. But they give up plenty of other things, chasing dreams that most will fail to achieve.
