I think the #2 QB battle might be interesting. I figure they'll keep Anderson because he's the type of QB that could win you a few games in the middle of a season if Cam misses some time, but Joe Webb is an interesting prospect that might push for the #2 job.
Otherwise, no surprise to see Cam a bit rusty...if there's a time to be rusty it's in mini-camp in June.
If you have anymore thoughts of Joe Webb winning the #2, you need to go back and watch the "highlights" of the Vikings playoff game he started.
Hopefully he'll get some looks as a WR.
