No, Girardi is just that bad. If Tampa keeps making their shots, the Rangers are finished, because they are not going to stop Kucherov-Johnson-Palat - that line gets a scoring chance almost every time they're on the ice.
And if they get a handle on that line, it's probably at the expensive of Stamkos/Killorn line, and vice versa. They don't seem to have enough to handle the depth Tampa is throwing at them.
Looking at their 4 lines right now, their forward depth is actually kind of amazing and underrated. They're every bit as dangerous as Anaheim or Chicago.
