Players, coaches, & staff are NOT going to to bars. That's an ignorant statement. They are not interacting with the fans, most of their team meetings are on Zoom, and the press conferences are virtual. They get put on the protocol list for GOING TO A TEAMMATES HOTEL ROOM, for f#$% sake! When the teams are on the road they are sequestered in their hotel rooms. When the team is at home they are at their home.
There is no way to tell how someone got infected with this virus. They could've been infected by the asymptomatic bus driver whose asymptomatic wife picked it up at the grocery store because she needed toilet paper. It isn't like you can look at their shoes to see who tracked the mud into the house.
