Mike Kafka's lack of arm strength "would be an issue" if he had to play extended time, according to ESPN's Dan Graziano. Kafka has the backup job sewn up, but it wouldn't be a smooth transition if Michael Vick got hurt. The 2010 fourth-round pick out of Northwestern is more of a dink-and-dunker, lacking the ability to get the ball deep to DeSean Jackson or Jeremy Maclin. We wouldn't bother "handcuffing" Vick with Kafka.
