Detroit's moves

I like their first day aggression.  They made two moves to improve their defensive line- the signing of Kyle Vanden Bosch and the trade for Corey Williams.  By my estimation, their quarterback pressure was 29th in the league.  Plus, they were gashed in the running game.  Also, the signing of Nate Burleson was a coup.  They needed to increase the number of targets Matthew Stafford to throw to.  He's a talented deep threat, and will be able to take coverage away from Calvin Johnson.  This is a good start, and they need to follow up with a good draft.
