However, he also made an unpredictable play that left fans, including coach Sherrone Moore, concerned.In the first quarter, during an RPO play, Underwood handed the ball over to Justice Haynes. He then made a block by putting his body on the line to help the running back score the team's second touchdown of the day.Moore talked about this play from his quarterback in the post-game press conference. He sent a blunt message, asking Underwood not to make any more risky defensive plays."I said stop, don't do it," Moore said. "(It makes me cringe) a little bit. But, I mean, he loves it. He loves the game. He loves football. He loves the physicality. He's the first one when we're having our nine-on seven drill tackling, he's over there getting hype, rocking his har, music. "So it does make you cringe when you don't want your quarterback doing that, but it kind of perks you up a little bit, understanding and knowing he loves that part of the game."
