Chicago Bulls center Nikola Vucevic had barely finished reading his email on Nov. 11 — the word positive was enough — before he started kicking several members of his very large – and very large – Montenegrin family out of his house. He would be forced to miss a big West Coast road trip for the Bulls, but a Thanksgiving surge of Covid cases was expected to arrive, the team doctors had told him, so he got the Vucevic clan packed up for a vacation to Florida without him. And he was just about to get his booster shot.
