The Celtics picked up a former national college player of the year in Luka Garza. Here's a few things to know about him.

Garza's two-year deal comes after the Celtics lost Luke Kornet to the Spurs, and could potentially lose Al Horford as well.

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.
