When you consider Austin's run of basically 3 yrs of hamstring problems now, along with his contract then WR shouldn't really be considered a "luxury" pick.
Since Romo became the starting QB these are the WR's we've drafted:
2007 Isiah Stanback 4th
2009 Manual Johnson 7th
2010 Dez Bryant 1st
2011 Dwayne Harris 6th
2012 Danny Coale 5th
One first day pick on a WR since he took over as the fulltime starter. Williams is the 2nd.
