President Trump has had a long association with sports, starting as a baseball player in his youth, and more recently as an avid golfer with something to say, often incendiary, about athletes and leagues.
But the Biden White House is likely to bring a lower temperature when it comes to commentary and influence on issues related to sports, though not a lack of interest. President-elect Joseph R. Biden Jr. was a high school football player and dabbled in baseball and track and has pledged to dismantle Trump administration policies that, in his view, negatively affect transgender athletes’ access to sports and the way sexual assaults are investigated on college campuses.
Although Mr. Biden has not worn his sports allegiances on his sleeve — as Mr. Trump and many politicians have — playing fields have often intersected with his life, going back to his childhood, when sports provided a universal language of communication while he managed a stutter. He served as vice president under a noted sports fan, President Barack Obama, who this summer counseled N.B.A. players who boycotted playoff games in a protest of the shooting of Jacob Blake.
“You see these two things happening in his life at the same time,” Evan Osnos, the author of “Joe Biden: The Life, the Run, and What Matters Now,” said, referring to Mr. Biden’s high school days. “One, he’s breaking the back of the stutter, and two, he’s finding his place on the football field. Those converged to give him this altered sense of himself, and that’s really the beginning of what was at that point almost a ludicrously ambitious notion of what he might be able to do in life.”
Mr. Biden celebrated on the field when the Philadelphia Eagles won the Super Bowl in the 2017 N.F.L. season. The Washington Nationals have already invited him to throw out the ceremonial first pitch on opening day. (The White House declined the Nationals’ invitation for Mr. Trump to throw an opening day pitch in 2017, citing a scheduling conflict.)
