When in doubt, 4-4-2.
Whilst i'm watching?
If neutral teams are playing: (like the superbowl) Enjoy the match for what its worth, possible route for the underdog if I can feel that they want the victory more.
If 1 of my weaker teams are playing: (Like Jaguars or the Suns) Enjoy that I get the chance to witness a match with 1 of my teams, I can't really watch a lot of there matches so it's a nice treat to stay up til stupid O'clock to just watch them.
If 1 of my stronger teams are playing: (Like Man City, Canucks and maybe the Brewers if they keep winning) Hope to god that this is finally the year 1 of my teams wins the big 1. I just want a good performance for all players with no weak links so I can at least say if we lose, we lost to the better team on the night. But most of all scream the house down when we score/win.
