The Los Angeles Rams pursued a trade with the Oakland Raiders for Khalil Mack before he was dealt to the Chicago Bears.

Oakland acquired two first-round draft picks, a third-round pick and a sixth-round pick for Mack.

“We offered a pretty aggressive package and they came back and said, ‘We just think you’re going to pick too low,’ ” Kevin Demoff said about the Rams’ potential pick in the 2019 draft.

The Rams will play the Raiders in Week 1.
