The greatest player in Spurs history is returning as an assistant coach.

Tim Duncan, who retired just three years ago, is officially a member of Gregg Popovich's bench. The team made the announcement yesterday according to CBS Sports.

It's not fully clear what his title is quite yet, but over the last few years he has been an assistant coach of sorts. This is just making it a little more real. Pop's putting a ring on it.

"It is only fitting, that after I served loyally for 19 years as Tim Duncan's assistant, that he returns the favor"

-Gregg Popovich

The future Hall of Famer was part of all five of San Antonio's Championships, winning three Finals MVP awards. He holds just about every team record there is, but you can't measure the guy's character. He's often considered one of the most coachable players of all time, something that will hopefully rub off as a coach.

We'll see what kind of immediate impact Duncan has on a team that has been eliminated from the postseason in the first round the last couple years. Hey, you can't make it to the finals without Tim officially a member of the team.
