But HoopsHype also reported the Bucks have "significant interest" in signing Dieng to a new deal.Dieng's qualifying offer would have been $8.7 million, but the Journal Sentinel previously reported the team wasn't likely to go that high and would prefer to offer Dieng a multi-year deal at a lower number.The 23-year-old Dieng was acquired by the Bucks at the trade deadline and was lauded as a quick learner. He played in 30 games with Milwaukee, starting 20, and averaged 11.0 points, 4.6 rebounds and 3.6 assists per game.Dieng scored a career-high 36 points against the Houston Rockets on April 1.This article originally appeared on Milwaukee Journal Sentinel: Bucks decline qualifying offer to Ousmane Dieng, interested in new deal
