If this pans out to be true, I'm reasonably excited about this addition. The guy has shown a fair amount of talent, and regardless of being the "worst" on the Packers' line, he's most likely still an upgrade for us. A Tweet I read earlier today made it sound a lot like the depth guys they have there are pretty talented, so it's nice to pick up a guy that beat them all out.
However, his Twitter says that he'll make an announcement when the decision is done, and he's not going anywhere yet. That was a few hours before this was posted, so it might not be entirely true, but I'd be disappointed to see him go elsewhere.
