Gotta be real careful with this stuff....it's too easy to cross the line.There's been a ton of good suggestions in here, but the most effective way I've found is the inclusion of other prizes.High score winner every week(reg. season only)....value about 20% of the yearly fee. A yearly high score (regular season) for about 2/3 of the yearly fee.Then, all teams not in the playoffs are matched up in "bowl games" for one extra post-season game. The prize for each game is about 1/4 of the yearly fee. (I match up the teams to make the games as even as possible)The idea behind it all is that it only takes one great week to get a nice chunk of your fees back. The bowl games help make sure that every team continues to look for ways to get better, because they will have a nice prize if they can win their last game.Over the last 3 years using this system of prizes, I've never had anyone try to tank a season, or trade stupid at the end because they were already "out of it"Of course, this will only work if your yourly franchise fees are high enough to make the weekly and yearly prizes worthwhile. (OUrs is 150 per year, with 30 for weekly prize, 110 for years high score, and 40 for each bowl game)
