Owusu-Ansah is another small school CB the Cardinals might go to in this year's draft.  He could not only add some depth to the secondary but also replace Breaston as the punt returner.  He did well at the combine and better at his pro day, at Ohio State, where he "stole the show" (Actually played at Indiana University, Pennsylvania).  He's projected 2-3 round. Here's a link to an article on sporting news with a quote from Rod Graves and  comments about DRC and Toler:

It's not clear if the quote is directly about Owusu-Ansah or not.  Here is a link to a highlight reel:

He's 6' 5/8"  207 lbs and runs through Div II tacklers like weeds.  On his pro day benched 225 lbs for 21 reps with a torn labrum in his shoulder.  It's had surgery since and should be healed by camp.  Opinions on his skill set vary but every report I've read agrees on his raw ability.  He's big, fast, and according to some has the makings of a shut down corner.
