The addition of Garza will soften the blow of losing Kornet, but Boston will need to do some work -- potentially a lot -- to shore up their big men.

The Celtics signed not one but two former Timberwolves bigs at the start of free agency to add to the depth of their roster.

The 6-foot-8-inch forward, 22, appeared in 46 games for Minnesota last season, averaging 2.6 points and one rebound while shooting 48.9 percent from the field.
