The San Francisco 49ers host the Minnesota Vikings on Monday Night Football as the second game of the season-opening double-header. The later game schedule means we get the Chris Berman, Trent Dilfer duo calling the game. As long as they are not talking about serious topics, one upside to this duo is they seem to love the 49ers. Berman has been positive about the 49ers from day one, while Dilfer reportedly is pretty close with the front office. So I suppose that's something positive for 49ers fans watching them on Monday.

Dilfer does film study to prepare for his announcing assignments, and on Tuesday he tweeted out all sorts of thoughts. There are a lot of tweets, so I thought I would break them up into a few topics. It is safe to expect Dilfer to bring up some of these points on Monday, so it is interesting to see where his head is at.

Given Dilfer's quarterback background, I figured we should start with his thoughts on Colin Kaepernick. There is a lot of praise, but he includes some areas of concern, which balances it out to some extent.
