We all know there is a huge amount of luck involved in this game. I'd offer two thoughts on that:
1) As my HS basketball coach Mom always use to say, "Luck Success is what happens when preparation meets opportunity." The better prepared you are, the better chance you have of maximizing opportunities when they come around, and consequently the more luck success you will have.
2) I highly recommend payouts to the teams with the best reg. season record and most total points. Both of my main leagues have significant payouts to best reg. season winner and numerous other categories. This balances out the luck factor a little bit as you are rewarding more that just the team that is able to go on a 2-3 game win streak at the end of the year.
Anybody can get lucky for a few weeks or even a season. But my experience has been that the better owners- the ones who spend more time, do more digging, and have better football/FF acumen---are the ones who are consistently in position to compete for championships.
