Three NBA teams are readying to make unrestricted free agent center Al Horford an offer he can't refuse. The New Orleans Pelicans, LA Clippers and Dallas Mavericks are reportedly preparing to make Horford a massive offer this summer, according to Ric Bucher of Bleacher Report.

Horford was reportedly interested in re-signing with the Celtics, but soon after he opted out of the $30.1 million owed to him for 2019-20, reports came saying he was planning to move on because other teams were willing to pay up.

Big Al enjoyed one of his best all-around seasons, posting 13.6 points, 6.7 rebounds and 4.2 assists per game, coupled with 1.3 blocks and a sliver under a steal per game.

Horford's effective offensive game (53.5% from the field, 36% from 3, 83.2% from the foul line), leadership and veteran savvy are viewed as highly coveted attributes that these three teams will look to add this offseason.

The Pelicans have plenty of young blood in their lineup after trading Anthony Davis and could use a veteran who can help guide a star in the making like Zion Williamson, along with other rookies like Jaxson Hayes.

The Mavs traded former starting center DeAndre Jordan in the deal for Kristaps Porzingis. Adding Horford would give two young talented players in Luka Doncic and Porzingis not only a mentor, but a solid frontcourt partner to finish plays at all three levels.

The Clippers have seemingly backed off from acquiring Kevin Durant, and if they only muster one star in free agency, coupling him with Horford would make for a playoff-bound team under a terrific coach in Doc Rivers.
