As a Murry proponent, I'd still love to fleece the Raiders.
Many smart people have pointed out, that the more picks you have, the greater chance a team will hit on some.
Imagine trading down to 4, still getting Q Williams or Ed Oliver. Getting one of the Raiders other firsts and adding N'Keal Harry. Drafting Chris Lindstrom with the Cardinals 2nd and Deebo Samuel with the Raiders second.
As much as I like Murray, a haul of:
Q Williams
N'Keal Harry
Chris Lindstrom
Deebo Samuel
You get a really good 3-4 DE, two good young WRs to pair with Fitz and Kirk, and an offensive lineman who looks like a ten year starter at LG. I didn't mention TE, because frankly, I don't know how important TE is going to be in a KK offense.
