Giannis Antetokounmpo. Runner-up Tom Brady
The year really came down to this choice - Brady winning another Super Bowl, with a new team, is the biggest accomplishment of the year, and then he came back in 2021 and continued performing near the top of the league.
But the single best performance of the year was Giannis in Game 6 of the NBA Finals, 50 pts, 14 boards, 5 blocks to win the chip. It capped off a ridiculous NBA Finals with 3 40+, 10+ rebound games.
