I'll say this -- Wade sees a division that does not have any dominant ballclubs, and he's taking a big stab under the premise of "anybody can win this." There is validity to this theory, and I don't fault him for wanting to try and make a run when he has an Oswalt/Lee/Berkman/Pence core to build around.
That said, he has gone about it in all the wrong ways. Look at how some of the other division teams have gone about their business this offseason:
Cubs (current favorites, in my opinion) -- Kept their division championship team largely intact, and addressed their biggest need (OBP) by unloading Jacque Jones and adding Kosuke Fukudome.
Brewers -- Have not traded a single piece of their young core away while attacking their bullpen weakness. Are in pursuit of a 3B that would fix the team's other glaring weakness (IF defense) by moving Braun to LF.
Reds -- Added Cordero, helping a major bullpen issue (albeit at a hefty price). Are in puruit of Erik Bedard. Have kept their talented offense intact.
In other words, these three teams have focused on their major needs. Houston isn't doing that, at least not yet. They added a SS on the decline (and are taking a significant defensive hit to do it), a 2B at good money who's really no better than the now departed Chris Burke, they've have traded away their two best bullpen arms, and have yet to add a starting pitcher to an awful looking rotation. They did all this while draining their farm system of any remaining potential talent and eliminating all their decent trading chips (including Luke Scott). I don't know, that Tejada/Valverde/Bourn trio needs to come through absolutely huge to make it all worth it, and even then I don't know that their rotation can keep them afloat.
