I'm still a bit unsure which position the team views is Bowie's and Bailey's best, but it makes sense to add tackle depth/competition. I feel it's as big of need as wide receiver personally and worth a first round selection. Bowie showed improvement at right tackle but was continually abused against tough competition. I'd be concerned to pencil him in as starter. And I know Bailey payed well in preseason, but he's way to unproven and is he a guard or LT? Did he even play any RT in preseason last year?
I mentioned it in another thread, but I really hope Seattle drafts a pure swing tackle who can play both sides instead of the James Carpenter-types who is the RT or LG type.
Let the rookie and Bowie compete at RT and keep carpenter at LG as the starter. If the rookie wins out against Bowie in pre-season then you have a solid backup at RT/LG. Heck, maybe even Bowie can beat out Carp at LG (he did start against the Saints playoff game).
In terms of prospects, I'll be watching tackles when I get the time, but I've got my eye on Morgan Moses who has a lot of starting experience and great size and length. He played 3 years at RT then his senior year at LT, so he's got that swing capability.
I know Joel Bitonio is getting a lot of talk with Seattle fans, but he's come out and said himself that about half the NFL clubs he's talked to view him as a guard/center at the next level with the other half willing to try him at tackle first and move him if he can't handle it. I like the versatility, but personally I want an anchor at the RT, not a guy who's best position is guard and is a maybe at tackle.
