To me, I'd see it as a positive.
Short term: Joeckel upgrades us at a OG spot. Glowinski didn't fare too well there. I don't care re: LT or LG.
It's also important to remember, that we signed Joeckel on March 9th. That was also before we tried to sign TJ Lang, who we offered on the 11th, but took Detroit's deal on the 12th. So Seattle was looking to load up at both OG spots in a big way. Seattle was primed to allocate 20M to LG and RG for 2017. Clearly Seattle is changing their roster formula as well as willing to change how we win as our defense ages and no longer plays at their current efficacy.
In the short term, this is encouraging. Seattle understands that our blueprint for winning will be to leverage Wilson's prime years of his career. It wasn't for lack of will, or lack of commitment of cap space that saw us lose out on Lang.
Long term:
It remains to be seen what 2018 may hold. Right now, the fact we were willing to pay Lang at the top end of the OG scale bodes well for the prospects of retaining Britt. Joeckel's contract is such that at worst, Seattle can simply allocate what we were paying Joeckel and Britt in 2017 to just Britt in 2018. Adding a quality OG via the draft is not remotely out of the question. It doesn't even necessarily require a end of R1 selection to do it.
Joeckel (and his contract specifically) could at worst be considered a cap placeholder for keeping Britt. And Seattle can afford to be patient with Britt -- allowing him to really cement in the FO's opinion of him going forward. At best, Joeckel succeeds and becomes worthy of a 9-10M per year contract. Seattle was already willing to pay unknown Joeckel and Lang 20m per year. It would seem logical that in 2018, they would be willing to pay a good Joeckel and a good/great Britt the same.
Right now, I love the fact that Seattle is showing a willingness to spend on the OL. Particularly since Britt, if he plays similarly to last season, is demonstrating a player worth retaining at market value. Something that couldn't be said for the OL we've let depart. Coupled with what appears to be a very marked shift in what we look for from rookie OL talent (Pocic), I think there is ample reason for fans frustrated at Seattle's approach to the OL thus far to be optimistic going forward. More willingness to keep the guys worth keeping. Better ability to identify true quality in draft prospects instead of great athletes with little to no skill.
I like the new approach. And I hope it's successful this year such that Seattle continues to get away from the approach that has resulted in large scale failure.
