You've definitely have the potential to be #1 this year. What place did you draft in your league?
I'll be interested to see how Dave Roberts does. Of course he's back in his hometown, but his batting is sub-par for a leadoff hitter. His speed will help, if he can forget that he's 32.
Bret Boone is someone else a little scary. At 35 or so, he's coming off a .251 average. This year, he's basically playing to stay on the mariners.
You've got a ton of classics though in I-Rod and A-Rod. Same with Abreu and your pitching core.
Look too see if Chase Utley or D'Angelo Jimenez are available at 2B. These are only to be used if Boone dives this year.
