15 players the Dallas Mavericks signed past their prime

2. Charlie Villanueva

Charlie Villanueva only spent two years in Dallas, but let's face it, it was way past his prime.

The Mavericks signed Villanueva to a one-year deal in the summer of 2014 and then re-signed him the following summer. After that second year in Dallas Villanueva retired from the NBA.

In 11 seasons in the NBA, Villanueva averaged 10.4 points, 4.6 rebounds, and 0.8 assists per game. His best seasons came with the Milwaukee Bucks and Detroit Pistons, as he was a valuable role player in his first few years, but in his last few years in Detroit, his numbers started to nosedive.

Villanueva didn't play like the player he was before, and his shooting numbers dipped astronomically.

He shot a combined 37.9 percent from the field and 33.1 percent from three in his final three seasons in Detroit. After playing in Detroit, he signed with Dallas. In two seasons with the Mavs, Villanueva averaged 5.7 points and 2.4 rebounds per game. He had a limited role, and he didn't play well when he was on the floor.

Villanueva's prime was short, but he did average double-digit points for six straight years before his downfall during the back half of his time in Detroit. He also averaged over 16 points per game in the 2008-09 season.
