Is Casillas going to be our Week 1 Starter?

I'm surprised this hasn't been talked about more. Casillas didn't even make the trip to Buffalo for the third pre-season game because he broke a rule, which I'm sure Lovie is not happy about. In addition, Casillas was the only starter besides Omameh and Cousins, who started on Thursday against the Redskins, so I definitely don't think he's a guaranteed starter come next week. Lansanah has had a very solid camp and pre-season, and I think he may be able to take the starting spot away from Casillas for week 1. Thoughts?
