Jayson Tatum's viral workout video sparks debate among Celtics fans

Tatum's offseason clip lights up social media

It's officially that time of the NBA calendar when a single training clip can dominate the timeline for a full day. On Monday, the Boston Celtics posted a short compilation of Jayson Tatum going through one of his summer workouts, and the internet did the rest. The post has already racked up more than 250,000 views on X, turning a routine offseason drill session into the latest flashpoint for Celtics fans.

What's actually in the video

The clip is broken into four separate moments, and each one shows a different piece of Tatum's game being sharpened before training camp:

• A one-legged 3-pointer that's drawing the most reaction by far
• A smooth fadeaway jumper
• Several catch-and-shoot 3-point makes
• Time in the weight room

The one-legged jumper is the shot everyone's talking about mostly because it's not a completely new addition. Tatum has actually attempted (and made) that exact shot in real NBA games before, which is part of why it's stirring up such strong opinions rather than just being written off as a gimmick.

Celtics fans can't agree on whether it's worth the practice reps

The comment section under the Celtics' post turned into a mini debate. Some fans defended the drill as a sign Tatum is refining his shot diversity heading into the new season, with a few even sprinkling in early MVP talk. Others weren't buying it at all.

• "I hope he doesn't try that one-legged jumper," one fan wrote. "He tried that a couple times last year and they were duds."
• "Tatum out here only able to shoot one-legged 3s. The Ls keep piling up for the Celtics," another user replied.
• "He genuinely trying to add a one-legged three to his game," a third commented, punctuating it with a heartbreak emoji.

Putting the one-legged 3 in perspective

Boston certainly wants Tatum to be a more consistent 3-point shooter than he was last season, when he attempted 8.9 threes per game and connected at just 32.9 percent. But context matters here: the one-legged shot fans are worried about barely moved the needle on his overall volume.

Of Tatum's 143 total 3-point attempts last season, only four were one-legged jumpers — and all four missed. In other words, whatever fans see in a viral offseason clip has almost nothing to do with the actual shot diet that will define his season.

The bigger picture: viral offseason clips rarely predict much

This is a good reminder that NBA players go viral every summer for moves and drills that rarely show up meaningfully once the games actually count. Tatum may pull out an occasional one-legged 3 here and there, but it's not going to be the shot that decides Boston's fate this season improving his overall efficiency and 3-point volume will matter far more than a single highlight rep from a July workout.

Training camp will separate the highlight reels from the habits that actually stick — and that's when we'll find out if this offseason clip meant anything at all.
