Indy based Mavs ~fan~ coming in peace

Hi everyone. As title states, I am a very disgruntled Mavs fan who lives in Indy and is planning on going to the Mavs/Pacers game soon. I’m wanting to bring a sign calling out the Mavs org and I’m wondering if anyone has any guidance for the most ‘heinous’ things I could write on a sign without getting it taken at Gainbridge? I know it seems like a silly question but pls have some sympathy for a very downtrodden fan 😔 with no outlet for this absolute shit show. I’ve been to games before but haven’t brought a sign and the most I’ve done is boo on occasion lol, so I’m not really sure how tough security will be especially if it’s technically against the other team. (And again just making it super duper clear not at all planning to say anything against the players bc I know that’s a no-no). Thanks in advance for any thoughts or insight!
