The No. 1 pick in the 2009 NBA Draft, Griffin will wrap up his career with six All-Star selections to his name, a Rookie of the Year Award, and placement on the All-NBA second and third teams on five occasions. In 13 total seasons, Griffin posted career averages of 19.0 points, 8.0 rebounds and 4.0 assists while playing for the Clippers, Pistons, Nets and Celtics.

Griffin (back) is available to play in Sunday's Game 4 against the 76ers.

Griffin was originally questionable due to low back pain, but he'll be available to come off the bench in this one. The veteran power forward has played just six minutes off the bench in the current playoff run, so he's unlikely to have a significant role here.
