Chicago will negotiate a long-term deal with Mack that is expected to trump the contract Rams defensive tackle Aaron Donald just received (six year extension for $135 million).
Since entering the league, Mack leads all players with 185 and a half quarterback pressures and ranks second with 68 tackles for loss, according to SportRadar.
The Chicago Bears have pulled off a whopper of a trade the likes of which the team hasn't seen in almost a decade.
"For me, it's been disappointing", Gruden said during training camp in Napa.
Mack and the Bears now have reached an agreement on a record-setting deal that will make him the highest-paid defender in the National Football League - a six-year, $141 million extension (a $23.5 million per-year average) that includes $90 million guaranteed and $60 million at signing, per ESPN.
Raiders players, including Mack's best friend, Derek Carr, have thoughts on this. "It was not the plan to trade him at all".
The 49ers also cut 2017 draft pick Pita Taumoepenu but made it clear they hope to continue developing him.
"They need to pay (him)", Raiders defensive end Bruce Irvin said on Live Instagram on Mack's account on Saturday. Chicago opens on 9 September in a prime-time game against Green Bay.
This is one hell of a bold move. Drafted fifth-overall out of the University of Buffalo in 2014, Mack is a three-time Pro-Bowler, two-time First-team All-Pro and the 2016 NFL Defensive Player of the Year.
Two first-round draft picks sounds great and all, but for the present, the trade would seemingly marginalize McKenzie in the decision-making process while upsetting the locker room. All that remains is to see what the damage is, wince ever so slightly and then get excited about the prospect of putting a 10-sack-a-year pass rusher on a defense that was already top 10 the year before.
Credit goes to Pace for pulling off the deal and also to chairman George McCaskey and president Ted Phillips for realizing the impact of Mack and what he could mean for the Bears.
