First, like everyone else this is great news. Macha is already asserting himself rather than letting the inmates run the asylum. I also love how he rejected Gallardo as his number 1 pitcher. Agree or disagree it's his decision and he's got an intelligent reason. I believe that Russ will be right, and that Rivera will not hold his offensive value as his at bats increase. But what if, slim as it might be, Rivera is a late bloomer and has turned himself into an above average hitting catcher. Then Kendall playing too much is effectively limiting Rivera's value, maybe by a lot (though again I admit this probably isn't the case). Given that Kendall is at the end of his career and Rivera is in the late middle part of his career, Jason could be hurting the Brewers by limiting Rivera's trade value. Lets pretend that Mike had 220 ABs last year and he hit .279 with 9 homers, and further lets pretend that this season Rivera hits .286 with 4 homers by the All-Star break. Now Posada goes down and the Yankees are in first place (I know, it ain't gonna happen, but lets pretend). Now Rivera may have established himels as a top flight back up, maybe even someone who could hold down a position for two months and not kill your chances in a pennant/wildcard race. We package Cameron with Rivera and in return we pry loose someone like Hughes because the Yanks are a little desparate. Now of course this isn't gonna happen, but my very small point is, is that if people are producing (like Rivera did last year) you must allow them to follow through because they could establish themselves as a valuable commidity. This is particularly important for small market teams because it gives them more flexibilty financially and talent wise. And again, you can't let some stubborn veteran have his way when it's deterimental to the organization's greater whole.
