But at least Mack didn't have the chance to directly terrorize his old club, which lost 33-13 to the Los Angeles Rams in its season opener.
Sean McVay proved last season that he's already one of the best coaches in the National Football League, earning Coach of the Year honors in his first campaign at the helm in Los Angeles.
NFL.com's Jeremy Bergman came up with three takeaways from the Rams-Raiders Monday night showdown.
But the Rams' defense made adjustments after the first half and posted a shutout in the second.
In addition to congratulating the team on its win, McVay also handed out a game ball to Marcus Peters, who had a pick-six in his return to Oakland, which is where he's from. So, it makes sense why the Rams didn't push harder to deal for the 2016 Defensive Player of the Year.
Peters now has 20 interceptions in 46 career games played.
Donald, who held out of training camp for a second consecutive season, said that he was prepared to play, but was unsatisfied with his performance. "I don't think we did a good enough job of putting a lot of pressure on him". They just want to get a contract they believe is fair.
