Today marks the first day that NBA free agents can actually sign with the teams they had to agreement with. While Al Horford and Kevin Durant were shaking up the NBA with their decisions to change teams, the Detroit Pistons spent their money wisely.

ESPN’s Marc Stein reports the Detroit Pistons are signing San Antonio Spurs restricted free-agent center Boban Marjanovic to a three-year deal worth $21 million.

The signing isn’t set in stone yet because the Spurs will have three days to match the offer once it is officially signed, but Stein is also reporting that the Spurs have no intention on matching an offer sheet for the Serbian-native Marjanovic.

Marjanovic, 27, appeared in 54 games in his rookie season, averaging 5.5 points and 3.6 rebounds in 9.4 minutes. Those numbers don’t jump off the page, but taking a closer look and it seems that Marjanovic will be a bargain for the Pistons. He averaged 21 points and nearly 14 rebounds per 36 minutes and is also a 76 percent shooter from the free throw line.

Marjanovic is also a monster of a man standing a 7-foot-3 and 290 pounds, and his mere presence causes issues for opposing offenses. This is a great get for the Pistons and offers them insurance for when backup center Aron Baynes likely opts out of his contract after next season.
