I think you're underestimating how much better Holliday is than Braun in the field. The Cardinals are a pretty average defensive club, while the Brewers are one of the worst in the majors. I viewed Suppan as a 5.5-5.75 ERA pitcher on the Brewers, and he may well be a 5.25-5.50 ERA pitcher on the Cardinals, although it will be lower when he no-hits the Brewers with 6 walks, 2 strikeouts and 3 home runs pulled back by Rasmus. I'll grant you Holliday is better, but unless he and Rasmus play 10 rows deep in the stands, he's not worth 0.25 runs per game. He's worth maybe 10-15 runs in a 162 game season over Braun. At best that's 1-2 runs per starting pitcher per season. That's a difference of less than .10 over 200 IP. The Cardinals are a +4.7 UZR thus far. The Brewers are a -25.4. That's thirty runs over two months. Now, I don't think the Brewers are as bad defensively as they have been, nor do I think the Cardinals are much better than average, but projecting them for a -25 and the Cardinals for a 0 from here out seems pretty reasonable, and that would be .25 runs per game. And how will having a good 1B and elite catcher not help Suppan? The difference between Fielder and Pujols is probably ten runs alone, and the difference between Kottaras and Molina is probably about ten runs as well, although that's a bit harder to measure, and could be significantly more.
