5 Al Horford replacements for the Celtics in the 2025 NBA Draft

2. Jarin Stevenson - Alabama

Standing at 6-foot-10, Jarin Stevenson is taller than some of the other big men on this list, and he’s very comfortable shooting the three-ball. He didn’t shoot particularly well during his freshman season, but at roughly 2.7 attempts per game, the willingness is there.

In his freshman season at Alabama, Stevenson only got to play 16.6 minutes per game, so getting to spend some time playing a larger role should do well for his draft stock this year, should he perform at a high level.

Stevenson is a quality defender with a developing three-point shot. Like Toppin, he’s projected to go late in the first round, which means he could technically fall into Boston’s range.

3. Adou Thiero - Arkansas

This would be a project for the Celtics, as Adou Thiero is still emerging as a player on both ends of the court after two seasons with the Arkansas Razorbacks.

Thiero just wrapped up a season where he played 21.3 minutes per game, which is up from the 9.5 minutes per game he played during his freshman year. The 20-year-old rebounds the ball well and is a solid defender all over the floor.

He’s yet to play a season where he’s shot more than one three-pointer per game, but he’s shot okay in the limited attempts he’s taken, clocking in at 32.3% for his college career. Thiero is projected to go late in the first round of early in the second.
