As someone who routinely makes the playoffs in fantasy, I have one rule that I've followed for the last decade.... never, ever put Dolphins on your fantasy team. As Dolphins fans we always expect more than we get on the field and it hurts you in fantasy.
I'm in the same boat. Buddies are always snagging Fins players thinking it will be good trade bait. Nope. Keep em. But, in my 14 person league, where you start to scrape the bottom of the barrel by that final round, Preston Williams might be my exception this year.
