​There are few people in this world that I would be more afraid of ticking off than Miami Heat president Pat Riley. He just looks so menacing and it's quite possible he'd rip your head off if you got on his bad side.

We can imagine he made a face similar to the one above when Tom Thibodeau tried getting greedy in a trade that fell through to send ​Jimmy Butler to the Heat. According to reports, he hung up on Thibs, straight up.

Not only did Riley hang up on Thibodeau, he even went ahead and called him a very, very bad word while he was at it.

But really, can you blame the guy? The Heat would be acquiring a star player, yes, but one that carries a hefty salary for the upcoming season and is a free agent at the end of the year. How much is Thibs trying to get when everyone in the ENTIRE league knows Butler will not be in Minnesota after this year?

Don't try to play hardball with Pat Riley. It ain't gonna work.
