I'm interested to see if any NHL players decide to opt out of the return as is now permitted and has happened in other sports. NHL players are generally more publicly reserved about playing for money instead of winning the Cup than athletes in other sports, but no doubt this will be a tough decision for some, particularly those whose families are expecting (especially their first) or those whose spouses work also. Possibly even a couple pending free agents who want to maximize future earnings without risk, though insurance provisions may cover that. No doubt the cultures are different, though.

Imagine if a high-profile pending UFA in the NHL opts out? Or a first line/pairing skater opts out for child birth or health concerns? The hot takes will be insane.

NBA
Trevor Ariza, starting G/F for the Portland Trail Blazers
Opting out due to custody battle for his son involving a one-month visitation window that would overlap the restart. The 'Blazers are fighting for a playoffs spot.

Avery Bradley, starting G for the Los Angeles Lakers
Opting out due to one of his sons having respiratory issues.
The Lakers have clinched a playoffs birth, sitting in first place in the conference and second in the league at the pause.
As committed to my Lakers teammates and the organization as I am, I ultimately play basketball for my family, and so, at a time like this, I can't imagine making any decision that might put my family's health and well-being at even the slightest risk.

Davis Bertans, utility F, Washington Wizards
Opting out due to injury mitigation. As a pending UFA, coming off a career-best season and with two previous significant knee injuries, Bertans doesn't want to risk an injury jeopardizing what will be the largest contract of his career.
The Washington Wizards are fighting for a playoffs shot.

Willie Cauley-Stein, C, Dallas Mavericks
Opting out as him and his wife are expecting the birth of their first child during the restart period.
The Mavericks are in a playoffs spot, but have not clinched.

Wilson Chandler, utility F, Brooklyn Nets
Opting out due to being a pending UFA and for family health concerns.
The Nets are in a playoffs spot but have not clinched.
As difficult as it will be to not be with my teammates, the health and well-being of my family has to come first. Thank you to the Nets organization for understanding and supporting me in this decision, and I will be watching and rooting for our team in Orlando.

Thabo Sefolosha, depth F, Houston Rockets
Opting out due to health concerns as a pending UFA.
The Rockets have clinched a playoffs birth.

In addition, DeAndre Jordan, of the Brooklyn Nets, will not participate due to testing positive for COVID-19.


MLB
I don't follow baseball but a few players have opted out of their season so far as well: Mike leake, Joe Ross, Ryan Zimmerman, Ian Desmond.
