The Boston Celtics are led by Al Horford and Kyrie Irving, but they also wouldn't be where they are without young players such as Jayson Tatum and Jaylen Brown.

Celtics head coach Brad Stevens is very impressed by what both Tatum and Brown have done thus far in their brief NBA tenures, saying that the two youngsters have had “ridiculous” starts to their careers, according to Jay King of The Athletic.

At 22 years of age, Brown is the elder of the two, and the Celtics originally selected him with the third overall pick of the 2016 NBA Draft.

Brown's playing time during his rookie year was rather scattered, as he played in 78 games but only saw 17.2 minutes of action a night. He then carved out a much more significant role in his second season, starting all 70 contests in which he played and playing a pivotal role in Boston's run to the Eastern Conference Finals.

He got off to a rough start this year, but since December, has quietly been very solid, and he is looking even better in these playoffs, as evidenced by his 19-point performance in the Celtics' Game 1 win over the Milwaukee Bucks on Sunday.

Meanwhile, Tatum was chosen third overall by the C's in 2017 and was one of the league's top rookies a year ago. He then officially broke out during last spring's playoffs, and while he had a relatively quiet season this year, he was still impressive, and what he has done thus far in this current postseason cannot be ignored.
