BOSTON — With no clue how to deal with COVID-19, the clowns in charge at NFL headquarters hit the panic button before sunrise in Broncos Country. So it’s a good thing Denver coach Vic Fangio is an early riser, or else he would’ve learned the league was aborting the team’s trip to New England while still wearing his pajamas. “I found out this morning roughly about 6:45 or 7 a.m.” Fangio said Sunday, when he arrived at team headquarters before dawn, with suitcase ready to go.
