Because the NFL is against selling a product ...

A player struck the Captain Morgan pose in the Eagles game. The NFL fined him because they didn't get a cut ...

The NFL will likely be a little more sensitive with this latest promotion, since it would have benefited Gridiron Greats, and the post-career struggles of players has been a paramount hot-button topic. While the league welcomes charitable donations to Gridiron Greats, it doesn’t want those contributions to be used as a carrot to influence the on-field antics of players – particularly when the antics center on selling a product.

God knows, you wouldn't want crass commercialism to get in the way of a football game, would you?

I think it was hilarious. The players should pose anyway and Captain Morgan should pay the fine AND pay the $50,000 to the retired players fund.
