As you know, Purdue fired three coaches once the seasons ended. That means it needs to make three new hires. You can only have so many assistant coaches on staff, but you don't have to have them all for specific positions (for example: Purdue did not have a quarterbacks coach, and now it does). The Boilers got rid of both coordinators and a position coach in Rubin Carter on the defensive line. In the various hires already made there has been some shuffling:
John Shoop was fired as Ofnesive Coordinator and Quarterbacks Coach
Terry Malone went from Tight Ends to Offensive Coordinator and Tight Ends
Tim Lester was hired as Quarterbacks coach (essentially trading a TE coach for a QB coach)
Rubin Carter was fired as Defensive Line Coach
Randy Melvin was hired as Defensive Line Coach
That leaves Purdue still looking for a defensive coordinator, and there are rumors that he, too, may be coming from Miami:
There has been considerable chatter that Mark D'Onofrio might wind up as the defensive coordinator at Purdue as well; but no confirmation on that just yet.
