Yes, he tries to frustrate the opponent and make him go toward him. Silva is just a dick, he was losing and he taunts, what a loser.
He was taunting to get Rashad to engage with him, and it actually worked out for him because he rocked Rashad hard. Unfortunately for him, he didn't have the gas in his tank to finish him. Rashad's gameplan, although boring, was pretty effective except he couldn't mount any offense on the ground and Thiago would just get right back up. From what I saw tonight, Rampage will absolutely destroy Rashad. If Rampage shows up in shape, his takedown defense will hold cancel out Rashad's shots and they will be forced to bang and I don't see him surviving a big left hook from Rampage.
