Pretend a team just switches their crappy 8 and solid 5 hitter around in the order. The 4 hitter is now "unprotected". His runs scored are going to go down for obvious reasons. His RBI's will also go down a bit because of intentional walks. In most cases, though, those intentional walks actually increase expected runs scored vs facing him Yeh, you don't have your better batters bunched up, so that hurts run production. But protection isn't about optimizing batter order, its about not having a good batter to put after your slugger to begin with. Long story short, your unprotected batter will produce less runs (R + RBI -HR) but your team might actually score more runs because the average IBB increases expected runs scored. Yes, there are specific situations where those IBB will hurt you. For instance, if it's the bottom of the 9th with 2 out and your team is down 1 with runners on 3rd and 2nd, the IBB will lower your odds of winning. As you pointed out, that isn't going to hurt the batter's rate states, though.
