The Denver Nuggets have made an offer to Milwaukee restricted free agent forward Luc Mbah a Moute, who is known for his aggressive defense.

The offer sheet is for four years and a little more than $19 million. The Bucks would have a chance to match the offer, but the source said that might not happen.

Last season, Mbah a Moute averaged 6.7 points and 5.3 rebounds. He's entering his fourth NBA season.
