Danny Green

When it comes to savvy veterans, it is hard to argue there being anyone more valuable that is still unsigned than Danny Green. With 15 years of experience in this league and having played with some of the greatest players and teams in NBA history, the fact that he is unsigned right now proves Green is being overlooked in a major way right now.

Beginning his career with LeBron James in Cleveland, Green got his start as a three-and-D player with the Cavaliers in 2009. From there, he joined the San Antonio Spurs and backed up the likes of Tim Duncan, Manu Ginobili and Tony Parker before eventually finding his way into the starting lineup and truly making a name for himself.

Danny played in back-to-back NBA Finals series in 2013 and 2014, proving his ability to perform on the biggest stage by setting what was at the time an NBA record for made three-pointers in a Finals series. After winning a championship in San Antonio, he took his expertise to Toronto and Los Angeles, helping the Raptors and Lakers to championships as well.

The low-hanging fruit take here is that Danny was just in the right place at the right time in his career. But in reality, he is a high-level role player with a strong head for the game and championship-level instincts and decision-making. He may not be the player he once was after some unfortunate injuries, but he would be a wonderful presence in the Celtics' locker room.
