No, as an official you have to maintain the same standard. A penalty is a penalty, whether it happens in game 7 or the regular season.
What about the crap call against Staal?
Detroit also outshot the Pens, whom only took 1 shot in the 3rd.
Same thing happened in Game 6. When you're up 2-0 in the third, you don't have to take as many shots.
