Based upon Braun's spring its obvious thats he an injury waiting to happen and should be traded immediately. Either that or spring training tell us little and the fact Braun has just been cleared to start throwing tells us that he probably could at least practice some defense before he ends up in Milwaukee.
The Red Sox have been looking to move Lowell, but they wouldn't have a use for Jenkins. Mench would be a better match, giving them a strong RH bat to play behind Drew and Ortiz and a decent fill in for when Drew misses his 40 games.
The Brewers can't keep all four those pitchers. They'll likely just be able to afford two of the four after 2008. Hopefully one will be Sheets and one of Bush/Cappy, but thats only if the team is lucky.
Anderson would have a possibility of a future with the Brewers if he was RH for a future platoon with Gross or in case of a Mench trade. But since he isn't, he's depth. His best hope is that he has a huge year in AAA causing him to get traded some place to get a chance to play
