Before linebacker Khalil Mack became a member of the Chicago Bears, things were pretty heated between him and Oakland Raiders head coach Jon Gruden. Mack was in the middle of a hold out and Gruden seemingly wanted nothing to do with Mack. According to Vic Tafur of The Athletic, the two have officially ended their feud. Gruden was coaching at the Senior Bowl and met up with Mack's agent Joel Segal. The two went out for dinner and before the night was over, Gruden ended up on the phone with Mack. Tafur reports that Gruden was full of compliments for Mack's strong season and Mack wished Gruden good luck with his project of rebuilding the Raiders. Mack of course had an incredible first season with the Bears and helped lead the team back to the playoffs. To top it off, Mack had 12.5 sacks in 14 games this year while the Raiders as a team had 13 total sacks on the season.
