Fortunately, few know exactly what Celtics superstar Jayson Tatum is going through after rupturing his Achilles tendon in Game 4 of the East semifinals against the Knicks. One member of the Red Sox does.

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.

The Boston Celtics were able to pull off a dominant Game 5 win over the New York Knicks on Wednesday night to keep their season alive. Even without superstar forward Jayson Tatum, who went down with a torn Achilles in Game 4, the Celtics looked the part of a team with championship experience.
