ESPN's Kevin Seifert says Christian Ponder's starting job will only be vulnerable if he "regresses or otherwise struggles" early this season.
Seifert is a former Vikings beat writer. Contrary to some earlier speculation, free agent Matt Cassel was not brought in for a training camp battle. Instead, he'll work behind Ponder and be at the ready. If Cassel turns out to be a better option in 2013, the Vikings are going to be in even more trouble than they already are.
