Jason Terry (2012)
Shortly after finally winning a championship with the Dallas Mavericks in 2011, the Boston Celtics, looking to add more supporting pieces for their Big 3, turned to Jason Terry to help find the formula to upend the Miami Heat’s Eastern Conference dominance. Figuring Terry had some previous experience in solving the Heat’s Big 3 during the NBA Finals, signing Terry seemed like a quality decision. Especially considering Ray Allen had also left (to sign with the Heat) in free agency.
And while Terry wasn’t “bad” for the Celtics, the dropoff in production was significant. After averaging at least 15 points per game in 11 of his first 12 non-Rookie seasons in the NBA, Terry averaged just 10 points per game on 43 percent shooting from the field in Boston. Terry was no longer the offensive weapon that he was during his prime and he looked more old than not on most nights for the Celtics.
Interestingly enough, after the 2012-13 season, the Celtics decided to tear everything down and hit the reset button. As part of the notorious Paul Piece and Kevin Durant to Brooklyn trade, Terry was sent to the Nets. Terry played five more seasons in the NBA before retiring. The Celtics probably signed Terry a few years too late.
