It was announced on Wednesday that the 49ers had signed WR Brett Swain. He's a good guy and I'm glad to see his career has continued elsewhere. Despite the season ending injury for WR Josh Morgan, Swain will only be asked to contribute on special teams. The 49ers also signed former Packer training camp invitee WR Kerry Taylor to their practice squad, which is making some news since he's the nephew of former 49ers WR John Taylor.
I don't expect Swain will break out with the 49ers, but he might become well liked once he makes a play or two. Taylor's best skill is as a kick returner, and they don't need that with WR Ted Ginn around. However, Ginn's a free agent after this season and they'd be much better off giving Taylor a chance next season then giving a long-term deal to Ginn (who's almost certain to underperform his contract).
On a related Bay Area note, after a small amount of speculation that LB Aaron Curry might be traded to the Packers, he becomes another reclamation project for the Raiders. It's a good deal for them (former high draft choice at a bargain basement price) but as Silver and Black Pride notes, he's a lot like the linebackers the Raiders already have. Curry will certainly get another chance somewhere, but it doesn't sound like Oakland is the best place for him.
