being that you are weak at 3b i like the right trade as it seems you need more help there and not at SS. wright's lack of power last year would scare me a little but you could chalk that upto zero protection in the lineup basically all year. so i'd say go with wright if you are going to do one of those trades.
I would definatly go with the wright trade as you are already strong as SS so theres no real need for Tulo and I think Wright's power will return somewhat this season.
14 team, 10 cat standard 5x5 H2H C-Wieters 1B-Fielder, I Davis 2B-Cano 3B-Reynolds SS-Lowrie OF-Bourne, Berkman, Rios, Torres, Wells (DL) SP-Kershaw, C Lee, Marcum, Chacin, Peavy SP-McClellan, Hudson, Collmenter RP-Sanchez, Crow, Bard
I would also go with Wright. Ramirez and Drew should be fine for you at SS and I really like Blanks potential. Wright's power should bounce back this year.
