NBA: Top 5 earth-shattering free agent signings in the recent past

4) LaMarcus Aldridge

Aldridge and the Spurs will continue to improve

In the 2015 off season, the San Antonio Spurs did something completely out of character. A team which had always stayed out of the frenzy of chasing big names in the free agency ended up signing the biggest name available in that year. By signing LaMarcus Aldridge to a 4 year, $84 million contract, the Spurs firmly established a nucleus along with Kawahi Leonard to carry the team after Duncan, Ginobili and Parker retire.

The addition of Aldridge made an already potent offence even more efficient. It took part of the season to integrate him into their offence, but soon he was popping for wide open jumpers which are a staple of the Spurs' excellent ball movement.

In the 2015-16 season, Aldridge averaged 18 points and 8.5 rebounds per game, even though he took a career low 14.1 shots per game. He shot a career-high 51.3% from the field last season.
