How would Michael Vick look as Colin Kaepernick's backup?Peter King of Sports Illustrated thinks he'd fit quite nicely. King pegs the 49ers as a "dark horse" candidate to land Vick, who will not be returning to Philadelphia. King writes that if Vick doesn't get any firm starting job bites, he could be interested in playing for a contender like the 49ers as a backup.It's a pretty interesting connection. Vick is a mobile quarterback, like Kaepernick.
