The Pistons will be Augustin's fifth team in four years. After a disappointing 2012-2013 season with the Indiana Pacers, he was waived by the Toronto Raptors in December. The Bulls then picked him up, and he completely turned things around, averaging 14.9 points and five assists in 30 minutes per game for Chicago and earning himself this contract.
Detroit will presumably use him as a backup behind Brandon Jennings, and at that value this is a solid signing in a vacuum. The Pistons have had a bit of a weird offseason so far, though, with this and the three-year, $19 million Jodie Meeks deal not fitting the usual mold for a rebuilding team.
