thielen would be a nice 3rd WR but he is getting up there in age.
Mmm reportedly he's not interested in a lot of teams and I don't think it makes sense. We've already got an aging receiver in Lockett and if we can improve the interior line a bit more (already done with Brown) and get another RB behind Walker that is reliable along with the tight end group (Dissly is doing pretty good on his recovery - didn't require surgery at least) then I don't think another aging receiver is really needed.
I'd rather have Thielen granted, over the bust that Eskridge is.. but I think some team with a new QB (there will be plenty) will cave and give him 1 year $7-8M, and Seattle simply can't afford that.
