So you want to trade Newman and Williams and pay their Guaranteed signing money and pick up another player who has a big contract?
I mean I like the player you want, think he is a good player and if there were no money issues involved it would be great...but I doubt Jerry would do that do to the contract/signing bonus moneys involved.
AND if you want to go about the premise that the Raiders can not afford another top 10 draft pick, you have them taking two players from us with large contracts so it would be counter productive moneywise in that scenario.
