The Detroit Pistons are finalizing deals to hire three new assistant coaches for Dwane Casey's staff, reports ESPN's Adrian Wojnarowski.

The list includes the Celtics' Jerome Allen, the Kings' Rex Kalamian and former Pacers assistant Bill Bayno. Additionally, the Pistons are expected to re-sign assistant Sean Sweeney to a new deal as well.

At 20-52, Detroit finished last in the Eastern Conference and with the second-worst record in the entire NBA.
