The Celtics center was so dominant on defense that Lakers coach JJ Redick acknowledged that his team’s approach turned out to be flawed

NBA offenses revolve around attacking weaknesses, and the Los Angeles Lakers thought they found one in Boston Celtics center Al Horford. They failed to realize the 38-year-old is actually one of Boston’s greatest strengths,

We saw this firsthand on Saturday night against the Los Angeles Lakers.

Fans take to social media to react to Al Horford nearly knocking Luka Doncic out during tonight's Lakers vs. Celtics matchup.

Luka Doncic had a huge game for the Lakers, scoring 34 points in the loss. He also took one of the biggest hits in the game when Al Horford hit him in the face with his knee after throwing down a big dunk in the first quarter.

Despite his age, Horford played 37 minutes for the Celtics. He ended up recording 14 points alongside nine rebounds and four assists. On top of that, his defense made life a living hell for the Lakers. Tatum even furthered his point by pointing out how valuable the Florida alum was to them.
