I would echo everything said here. The Kazmir trade was something of a symbolic turning for the fans who have followed the team through the slash and burn overhaul of the franchise, and, most importantly, it seems to be a shrewd move.
The ultimate outcome of the season is obviously uncertain, but the journey will be fun. Altuve, Correa, Keuchel, and Springer are guys that make watching baseball an exciting pleasure and portend a bright future for the org, and Luhnow has done a great job surrounding them with complementary pieces. Perhaps most surprising to me has been how it seems that such a young team has created a really positive clubhouse culture imbued with confidence and moxy--really nice to see them bust out of the 2nd half gate after waning into the break. There have been some ups and downs, as there are in any baseball season, but this team seems to bring it against the class of the AL.
