Somehow I stumbled across this t-shirt. It all came together nicely from there, and I did my best in recreating the image for my draft poster...
Of course, I had to include a description for all the non-D&D players in the league...

ALIGNMENT Lawful evil
Mind flayers are found only in domed stadiums, as they detest sunlight. They are greatly evil and consider the bulk of the DFL as cattle to feed upon.
The mind flayer's physical attack consists of the long ball threat as well as a formidable running game. Few can withstand the force of their offense. Most flee in the face of their terrible offensive power.
If an encounter is going against a mind flayer, they will dispute the rules and blame injuries to key players as well as bad calls by referees.
Description: The mind flayer's skin glistens with slime. Its skin color is a Nauseous mauve, its tentacles being purplish black. A mind flayer's eyes are a menacing red no pupil being evident. The three long fingers of each hand are reddish, but the hands are mauve
