Shaw is the 5th cb, same as last year. Two Rooks are ahead of him on depth chart counting Buchanon (technically a rook didnt get enough games to count full season). And Love started over him last season before an ankle sprain gave him PUP status to start camp for a couple of weeks before re-activating. Four others ahead of him.
He has played his share of playoff games (Chargers,Pats, and Raiders superbowls) or was the Charger SB before he was drafted?
Anyways the guy is solid but not dominant. Another journeyman.
As for Woodson, it looks like he is in career year form, if Grant doesn't show something as well as Gibson, their cap room will become Woodson's bonus money and he will be long term Raider when they get cut.
