For game day nutrition, these guys pretty much have it down. Hydration leading up to game time is important, and consume a carb-laden meal 2-4hrs before.
I will say this though - energy drinks will work for sporting activity lasting >1h. Even then, you don't want to drink everything, or you'll feel too full. In sports science, this is what we do for our teams: one bottle of water and one bottle of energy drink for each athlete per game. Water to be drunk throughout the game in sips, energy drink to be swished in the mouth and spat out. According to some research, just tasting the energy drink is enough to trick the brain into thinking it is consuming carbs and make the body feel more energetic.
I can't comment about tactics, but short shifts go a long way. Gas yourself out in the first period and you'll suffer the next two.
