I wasn't too excited about the Joseph signing, personally. But hearing what Demoff said the other day re: the Rams' DL take on Joseph and that he was one of the best OGs they faced all year, well, it made me feel much better about it.
If the Rams luck out with him it would be a big deal for this OL. He is a nice fit provided he actually has something left because you can't have too many physical interior OL when you live in the NFC West.
I'm still holding out hope that Jones is going to step up and push for relevance, at the least a primary backup job. He's really the wildcard IMO because the buzz won't start on a guy until he actually plays some snaps and handles dudes in camp with pads on. I fully expect that buzz to start with him at that point, because given his track record he's gonna show up. And while I am with those who see him at center eventually, remember that he has played OT before and may have the feet to play RT.
The OL is going to be very fun to watch develop this time around.
