First of all, they need to COMPLETELY eliminate the call of unsportsmanlike conduct DURING the play...
For instance, last bowl season, in the KU game. Dont remember who it was, but he got called for highstepping into the endzone.
This is complete BS, if the defense can't even come close to the player with the ball, they deserve to get taunted.
Now, on to after the play. If it is a short celebration and it does not delay the game in any way at all... then why not?
Like the flag thrown today after that sack... it was like a 1.5 second celebration, involving 1 player. There is no reason that should have been called.
They are making it seem like the game should be played with no emotion, and you can sack the QB to stop a drive late in the game and you are expected to calmly walk back to the huddle...BS
