Interesting. Comments below that reflect ignorance. Play anywhere you want? How about, like any other pro sporting venture, you are part of a league/organization with rules you must abide by. Those rules are to protect that brand, making purses for players more valuable.
The longer this goes, the fewer folks who would be eligible to come back. Even fewer who you would want back, given a lot are past their prime.
No one is missing Talor Gooch, Carlos Ortiz, Joaquin Niemann, etc. and the guys you do miss are really no longer contenders, save Bryson and Brooks.
