I haven't seen any Vikings games this year, but I'm still fairly skeptical.
I seem to remember outside football fans who knew nothing about the Chiefs saying in 2010 that Cassel was a pretty good starting QB no matter what I tried to tell them.
Ponder's got the same kind of thing going on. Good news for him is that he's young and still learning. Ponder will likely continue to improve. How much is another story.
