I don't know if you're referring to me as one of these people, but I will say again that I think losing Vazquez is going to hurt. He is known as an elite pitch framer and he seems to handle the pitching staff very well. Pitchers have raved about him. Honestly, while the CS% is nice, CS% is not that big of a deal to me.
That said, I have also expressed my happiness about having Hanigan on the team since he was signed. In fact, I really wanted him signed last year over AJ or any other catcher. Really, really wanted him instead of AJ.
The point being, with Vazquez injured, I think the Sox have about the best case reasonable replacements available. I like things even better now that the Vazquez Clone has been signed.
That's not to say that losing Vazquez is no big deal. IMO, it is a bigger deal than most people think. This is a pitching staff that would have benefitted a great deal from Vazquez' skills. My posts yesterday were mainly in response to your false claim that Hanigan/Leon would not be a good defensive tandem. They will be very good, but they will not be as good as Vazquez/Hanigan would have been.
