To say the Khalil Mack trade isn’t going over well in Raider nation would be a huge understatement.

The Oakland Raiders on Saturday reportedly agreed to trade Mack to the Chicago Bears. The 27-year-old All-Pro pass rusher had been holding out in hopes of landing a lucrative contract extension.

The move is a true blockbuster, as well as one that new Raiders head coach Jon Gruden apparently was eager to make. Check out this tweet from Bleacher Report’s Mike Freeman.

Now, let’s talk about that second note.

Mack understandably was a popular player in the locker room, as the University of Buffalo product is one of the NFL’s elite defensive talents. And, well, let’s just say his departure isn’t endorsed by Raiders quarterback Derek Carr and linebacker Bruce Irvin.

Take a look at these tweets (Warning: Irvin’s contains NSFW language):

As Carr mentioned, deals like this are an unfortunate byproduct of what truly is a shrewd business. Life goes on, however, and the Raiders have enough talent to remain competitive, provided Gruden can get everyone the same page.

Still, Oakland will be hard-pressed to replace the production of Mack, who averaged 12 sacks over his last three seasons with the Raiders.
