Facing elimination and with Jayson Tatum sidelined, the Celtics kept their season alive in Game 5 against the Knicks.

On and off the court, Jaylen Brown stepped up as the leader the Celtics needed after Jayson Tatum’s season-ending injury.

While the injury shouldn't derail Tatum's career, it does give the Celtics a major obstacle to overcome. Boston has been to the conference finals five times and has had a pair of NBA Finals appearances—including a win last year—since 2017. Much of that success, especially over the past five or so years, has been largely due to Tatum.
