Detroit Pistons president-coach Stan Van Gundy said Wednesday the organization remains in contact with the representatives of swingmen Kentavious Caldwell-Pope and Reggie Bullock for possible contract extensions. The deadline is Oct. 31. If deals aren’t reached, the two players will be restricted free agents next summer. “We definitely have a desire to get something done with both of them,” Van Gundy said. “I think both agents are clear on that from our side. “It’s a matter of two things — it’s a matter of what they want to do and obviously it’s a matter of money, so that’s where the negotiations are.”
