1. Okung and Unger need to stay healthy and play up to their sub-elite talent. Both having down years, I would assume they'll bounce back in 2014 or they might not be here for the long term if the team feels they are becoming damaged goods.
2. Its easy to sleep on Carpenter and Sweezy and claim how horrible they are but I wouldn't.
Carp for the first time in his career as a pro can workout and condition over the off-season. If he can whittle his weight down to a healthy 315-320, he's going to be a monster entering his contract season. Does he work hard to earn starting money or does he linger and becomes a journeyman making back-up money?
Sweezy, is entering his 3rd year, and considering his process of development from where he came from as a rookie, I would ask you to take everything you feel about him and throw it out the door. Treat his first 2 years as an Offensive Lineman in the NFL like it was his 3-4 years playing in college, and now in his 3rd season is really like his true rookie season as an O-lineman. The guy has all the athleticism in the world to be special but its experience that's been holding him back.
As for Right Tackle. I also wouldn't sleep on Michael Bowie, Alvin Bailey, and Caylin Hauptmann all being thrown into the fires of competition and letting the best man win. Cable may not be the best O-Line coach in the NFL nor even great at identifying talent but the one thing he does do his take the talent he does have and slowly maximizes it while forging through toughness.
If you asked me were pretty well-off as long as our best players remain healthy and the younger players continue to develop. But you could literally say that statement about any position group in any sport.
I would contend that were a little thin at Guard w/o McQuistan but Jeanpierre, Bailey, and Bowie are all versatile.
It wouldn't surprise me though if the Seahawks signed a cheap, vet or two to "compete" like Lutui and Barron did in 2012 aka veteran "camp fodder".
Then draft/sign as udfa another 3-4 O-Lineman like 2013 except this time they won't be pulling the triggers in the 7th round but in the early rounds.
The more competion the better, keep all these guys on their toes and hungry for opportunity.
