As a die hard Husky I am thrilled. I hope USC enjoys great skill position guys with terrible O & D Lines. Our guys give up hits on our QB like he is candy and it is Halloween and our D Line plays like they think a Sack is a bad word. Seriously I am so fucking HAPPY!
It won't be hard for him to get quality lineman to USC at all. O-line and D-line are probably the 2 hardest positions to get elite recruits, WRs and RBs that run a 4.4 40 are a dime a dozen nowadays, but truly elite lineman are highly sought after. Washington just wasn't back to the point of being able to win battles for those guys consistently with Oregon and Stanford competing for the same guys on the Northern West Coast, but USC will be able to get basically whoever they want.
Anytime a program is being rebuilt from bad shape (Sark at Washington, Leach at Wash St and previous TTech, Harbaugh at Stanford, Pinkel at Mizzou, etc) it's always fairly easy to get a couple great skill guys and maybe a solid QB to get you back on the winning side of things with bowl games, but to truly take that next step to challenge for conference titles and national titles it takes those lineman and that always takes a little longer to develop a system that draws those guys in. That was Missouri's weakness in Pinkels first half decade or so, we just got man-handled on the lines by the likes of Oklahoma and Texas, even though we had some good skill position players. It wasn't until the last 5 or so years that he's finally attracting quality line talent(although some would argue that we still don't have it on the O-line, only the D-line, there's definitely room for improvement) Why does the SEC dominate so much over the last decade? Look at the lineman coming out of those states. Athletic 6-foot-5, 320-pounders grow on trees in the South.
tl;dr I think Sarkisian will do well at USC. Will he be playing in back-to-back national titles anytime soon? Probably not, but they'll be damn good again within the next year or two, challenging for the Pac 12 title. While Washington *could* make another good hire and not miss a beat, anyone who is actually happy to see Sarkisian go is crazy. The odds of making a worse hire are a lot better than finding an upgrade. his consistent 7-6 is nothing to write home about(8-4 this year), but keep in mind that Washington hadn't won 7 games in any of the previous 8 seasons before he got there. They were really, really bad.
