With the 27th pick in the 2008 NFL Draft, the San Diego Chargers selected cornerback Antoine Cason from Arizona. The Chargers will miss Drayton Florence in the secondary, but they will add to one of the best young secondaries in the league in Cason. He wasn't the highest-rated cornerback in the draft, but they are still getting a very solid player towards the end of the first round.
I do question not taking safety Kenny Phillips though, who would've replace Marlon McCree immediately.
