Aboz has some good points. Kendall is good offensive player, but is somewhat on the weak side defensively and his handling of ppitchers has been questioned, if memory serves me correctly.
We need a solid defensive catcher if only as a late inning replacement and to give Sandy a breather. Burke's flexibility gives Ozzie some options, too. Kendall's good, but that's a lot of jack they are paying him. Also, I'm not sure MLB rules would allow Pittsburg to pay any of his salary beyond this year. They can send enough cash to cover the rest of this year's salary, but the Sox would have the whole enchilada beyond that.
