Yes.
Say what you want about whether that was a "late" slide or not, that's the first time, I believe, that a DR led offense here had a chance to salt away the game and actually did it -- instead of doing something like going 3 and out or turning it over.
If it takes a late slide to win -- take the late slide.
I doubt anyone for BC was bitching about their QB throwing a bomb to their blanketed wideout late in the game in order to draw a DPI and automatic first down. You do what you have to in order to win.
