I imagine if Roenicke decided to bat Izturis behind Braun his numbers would change. Whether you have Fielder or Ramirez behind you, you're better off trying to deal with Braun than face Fielder or Ramirez with him on base. I wonder if you looked at the difference in outcomes for the same players when hitting 8th in front of a pitcher vs. up in the order in front of a competent hitter if you'd find that there is a significant difference. *Also, what I remember from the study I've read about "protection" is that it doesn't change a batters' overall production, but I'm not sure if I've read anything that indicates that how they put up the production changes, i.e. it could be that Braun is just as valuable, but he draws more walks, hits for a bit less power, etc.; just that those effects both even out, so to speak. I imagine somebody has looked into this and I imagine the conclusion would be that the effect is once again minimal, but I'm curious to know whether that's been looked at.
