For Bosa — who had just been fined $11,255, or .033 percent of his $34 million-a-year salary, for sporting a “Make America Great Again” hat on the field weeks earlier — it was, evidently, an emphatic if tongue-in-cheek salute to the president-elect. The lumbering gestures of politicians rarely trickle down to the football field, but this instance made for a strange kind of harmony: Trump, after all, has perfected in politics exactly the kinds of gloating theatrics we expect from athletes after just about every net-positive play.
