Boston Celtics head coach Brad Stevens admitted that he will always be wary each time he faces a team led by LeBron James. He made it clear on Saturday, prior to the Celtics' hosting of the defending champions Los Angeles Lakers at TD Garden.

Per Tom Westerholm of Boston.com, Stevens compared The King to another aging all-time great in a different sport, Tom Brady of the Tampa Bay Buccaneers in the NFL.

“I’ve learned not to doubt the greats of all time. Everywhere I turn right now, everybody wants to talk about Tom Brady here in New England. He’s 43 and going to another Super Bowl. The bottom line is if anything, LeBron has continued to improve … There’s not many guys who can play like that, this well, this late, but there weren’t many guys like him before he got to this point.”

There's no question the Lakers superstar has emitted greatness ever since he stepped foot in the league in 2003. Eighteen seasons later, he's still going strong and has defied Father Time again and again. Having faced LeBron-led teams numerous times over the years, Brad Stevens certainly knows that the four-time NBA MVP is still as capable as ever, even at 36.

Prior to Saturday's match against, LBJ is notching 25.4 points, 7.8 rebounds, and 7.5 assists per game, while knocking down 49.6 percent of his field goals for the Lakers.

Moreover, James has added even more facets to his game, as he became a much better shooter over time. He's draining a career-high 41.7 percent of his triples in 20 games for the Lakers so far.
