While you might technically be in the clear, if they actually brought a lawsuit and you wanted to fight it you would be on the hook for at least 5 figures worth of legal fees (probably more), regardless of whether you win or lose.
Anyway my team is the seahawks, but I would be interested in other teams too if they look cool
If you make any sort of reference to JJ Watt, whether it be his name, his image, or a white stick figure wearing a generic blue and red #99 jersey, they will come down on you hard.
And they have a lot more money than you do.
That's why I say... if this is legit, and these look good, and are unique, I might be able to make you a boatload of money.
