The belief was that you were allowed two pumps per touchdown celebration, but Antonio Brown wasn't even granted that this weekend.

Brown's coach, Mike Tomlin, wants some answers.

"We have to get some clarity in terms of what's legal and what's not," Tomlin said Tuesday . "I know he doesn't want it to be a negative thing. He wants to provide positive energy for us and entertain our fans. But we have to get detailed clarity on what he can and cannot do. You've got to acknowledge some guys are followed more closely than others. You saw that last night with (Odell) Beckham. AB is probably one of those guys, and he probably needs to respond accordingly."

Sunday night was the second time this season the Steelers receiver was penalized for dancing. In the first case, he had twerked too violently for the NFL's liking.

Brown isn't purposely trying to hurt his team by drawing these flags, he just likes dancing. But he's violating the league's rule that bans "sexually suggestive" celebrations. What does "sexually suggestive" mean? We can think of some obvious examples that shouldn't be allowed, but it gets complicated when you bring twerking into the picture.

Broncos receiver Emmanuel Sanders did a similar gluteus workout as Brown this season, but he went unscathed.

why are Steelers fans so upset I didn't get fined? Lol I don't understand the logic behind wanting a man to get fined for dancing. #ohwell — Emmanuel Sanders (@ESanders_10) October 1, 2016

The double standard doesn't seem to make much sense, and it's not affecting only Brown. Josh Norman was flagged this weekend for "shooting a bow and arrow," which has been the end zone celebration for Saints receiver Brandin Cooks and something Chiefs players have done for multiple seasons.

Why was Norman the only one to get penalized for it? Partly because Mike Pereira snitched on him, but maybe Tomlin has a point. The big-name players are easier targets to draw this attention from officials.

Does this mean we'll see less dancing from Brown? We hope not. But if the NFL continues its "No Fun League" stance, then he'll have no other choice.
