For #1,

Given the opportunity to decide everything that is going on in the game, first of all I would make everybody play as goons, enforcers, and fighting maniacs (like Wilson, Khaira, Marchand and Reaves). Then, I would set the aggressiveness on everybody's tactics to its max, and tempo to very high. This would very much lead to about 2 rounds of very brutal hockey, which would land hits one after another. It would also fill up the penalty box quite nicely, so please expect plenty of penalty minutes per player per game. I would laugh at the end of the season to the fact that majority of the players in the league has more penalty minutes than points in general. Second, I would create a software based on the hack, which would randomize all players in each team. This could mean that one team could potentially have 15 defenders or 15 forwards, or even a skater playing as goaltender (because that was where he was assigned). It would be glorious, but at the same time chaotic evil as heck.
