Jayson Tatum's torn Achilles will have a profound impact on the Boston Celtics, but it could also change the landscape of the entire NBA.

It's hard to believe things could've gotten any worse for the Boston Celtics. As if gifting the first two games of the Eastern Conference Semifinals to the New York Knicks wasn't egregious enough, Jayson Tatum suffered a ruptured Achilles in the final minutes of Game 4.

Not only did the Boston Celtics lose to the New York Knicks Monday to fall to within one game of elimination from the NBA playoffs, they also lost Jayson Tatum to a lower-leg injury. Which means he may not be around to help them fight back from the 3-1 series deficit.
