	Dinwiddie was selected with the 38th overall pick by the Detroit Pistons in the 2014 NBA draft. He appeared in 34 games for the Pistons as a rookie, making one start and receiving two assignments to the Grand Rapids Drive, the Pistons' D-League affiliate. His lone start came on February 20, 2015, after a pair of trades left the Pistons short-handed. He had career highs of 12 points and nine assists in a 100–91 win over the Chicago Bulls. Eight days later, he scored a season-best 20 points to go with eight assists in 25 minutes off the bench in a 99–95 loss to the Washington Wizards.
