Coach Gruden collects QBs like most people collect baseball cards.  Josh Johnson is 6′2″, 200 pounds and he runs a 4.56 40 which shows what kind of athlete he is.  He has not played against much competition in college but he was dominating there.  Johnson played in 42 games (34 starts) at San Diego and he completed 724 of 1,065 passes (67.9%) for 9,699 yards with 113 TD passes and 15 interceptions.  He will likely take a few years to adjust to the speed of the NFL.
