It's beginning to sound like Mack getting traded is inevitable. The only question is to whom.
I really didn't think so at first, but I can't imagine Mack and the Raiders all of a sudden agreeing to a deal and it doesn't sound like he's just going to show up week 1 if he knows he could get traded to another team and get a mountain of money.
If you were him, and you heard all these teams calling the Raiders, each of which is ready to back up the Brinks truck for you, why would you even think about showing up on your current deal?
