I was upset yesterday after the early games and pretty much knew I was getting my rear handed to me in pretty much every league I play in. Then, my 2.5 year old son woke up from his nap and just wanted to watch football with daddy and was happy watching guys running, scoring TD's and being tackled. Put things in perspective for me.
Once your rosters are set, just try to relax and enjoy the games. You can't do anything about it and getting upset over a guy scoring 4 TD's against you isn't the best use of your time. It's frustrating, yes, but things could be much, much worse.
On Sunday's I generally make a big breakfast for my wife and son and I, do a little cleanup around the house and then sit down and watch with 1:00 pm games when my son is napping. After he wakes up, we watch some of the 4:00 pm games, eat dinner and then my wife and I watch the Sunday night game.
I'll usually check the stats at 4 and before the night game, but that's about it.
