The Vikings' signing of Matt Cassel on Thursday indicated to some Vikings fans that there might be a quarterback competition at Winter Park this summer. Not a chance, according to Vikings coach Leslie Frazier. "Christian Ponder is our starting quarterback," Frazier said during an interview with the NFL Network's Steve Wyche on Monday, March 18. "Matt knows that. ... He's coming in to provide insurance for us if something were to happen to Christian, injurywise. We'd have a quality backup who can step in and do a great job for us."
