If we're throwing out ideas, I'm a big fan of weekly small $$ prizes for overall top score. It keeps people invested and provides an incentive to stay involved even if your team is at the bottom of the standings - you can still always take home the weekly prize. I do this with the relatively small league I run for my office. It's only $10 per week, but it's something. A larger league I'm in was $50 per week. The problem, of course, is that you have to have a large enough buy in to fund those weekly prizes and still have enough left over for a decent prize for the champion and runner up. $100 per person gives you a pot of $1200 (less any expenses associated with the hosting site, if any) so that could be enough. Also, you could add the money from auctioning off free agents to sweeten the pot.
