Bell is a good closer, but you should never pay money for saves. Should have just used someone who already was in the pen to close. Buehrle had a 117 ERA+ which is solid, but, if you split his stats, he flourished in May, June, and July. When the Palehose were trotting out a six man rotation. Going to the NL he'll probably fare better, especially in that huge ballpark they're building (its enormous, check the dimensions for yourself). Jose Reyes, defending NL batting champ, and a pretty good player. But, his hamstrings have a history of being injured, and his biggest asset is speed. If his legs continue to be damaged, and he is starting to age, that is going to zap of his biggest asset. These contracts are going to bite them in the ass, and not to mention, they're back loaded so I doubt anyone takes them with Florida paying most of the tab.
Zambrano has a huge attitude problem, he's not a bad pitcher when he keeps his head cool, but he'll wear out his welcome fast. Ozzie is a loadmouth, classless buffoon who is a clubhouse cancer. Don't believe me? Ask a White Sox fan.
Marlins have a good team, but hot tempters (Hanley, Ozzia, Zambrano) its going to be a disaster, and an expensive one.
