Boston Celtics stud Jayson Tatum is one of the fastest rising stars in the NBA today. He has upped his level of play from his rookie debut season three years ago and has since been rewarded with his first call-up to the All-Star squad this season.

When asked about what the biggest improvement has been for him since entering the league, the 22-year-old's answer was not exactly one that you would expect.

The Celtics All-Star obviously got jokes, and he just dropped one on the mean streets of Twitter here. To be fair to him, the question did ask about a physical improvement he has had, so the beard thing does fall into place — somewhat.

In all seriousness, though, the 6-foot-8 forward has improved by leaps and bounds since being a highly-promising 19-year-old rookie in 2017. That season, the former Duke standout averaged 13.9 points, 5.0 rebounds, 1.6 assists, 1.0 steals, 0.7 blocks, and 1.3 triples per contest.

Compare those numbers to what he has done so far this season (23.6 points, 7.1 rebounds, 2.9 assists, 1.4 steals, 0.9 blocks, and 2.8 threes), and there's no denying that the overall improvement has been more than significant.

It is also important to note, though, that this is the first season that Tatum has taken the reigns as Boston's main man. The exit of former team talisman Kyrie Irving has undeniably had a huge impact on Tatum's improvements, with the offense now centered around him more.

Let's not forget that he is currently just 21, and all signs are pointing to the fact that he will only get better from here on out.
