I always name my fantasy football or baseball teams either Team Buzz (as in Buzz Lightyear) or Team TMNT (as in the Teenage Mutant Ninja Turtles). I get pretty in depth to the story line every year, sending out at least monthly "Buzz Updates" to the league via the message board or email. These updates usually announce roster moves and use Buzz and the TMNT in creative ways to entertain the league.
For example, usually around roster cut-down day (these are normally dynasty leagues!), Buzz loses his temper and uses his arm blaster to take out the camera of an unsuspecting media member, causing a player to get injured and subsequently cut from the roster. Also, if an NFL player is injured, I will make up a creative way he got injured in the fantasy league...normally by Buzz! A mime or two gets take out as well...
Anyone in a league with me can vouch for these updates and entertainment, going on now since 2000!
Hey, these aren't called FANTASY sports for nothing, people! Enjoy your fantasy!!!
