Brian Daboll knows what he did after the first play of the second quarter in Sunday’s 24-16 Giants victory over the Texans and, upon review, did not like the way it looked a day later.

“You see it after and you’re like, I wish I didn’t do that’ sometimes,” Daboll said Monday.

The regret from the first-year head coach emanates from his reaction — caught by the television camera, for all to see — after offensive lineman Jack Anderson was called for a false start. The Giants, leading 7-0, were on the Texans’ 36-yard line. Too far for a field-goal attempt, too close for a punt. Daboll decided to go for it on fourth-and-1 and onto the field ran Anderson, Nick Gates and Matt Peart, three extra offensive linemen for what was shaping up to be a power run attempt by Saquon Barkley to pick up the first down.

The play never happened. Anderson was flagged for the penalty and Daboll sent out the punt team. On the sideline, he absolutely lit into Anderson, who stood there, helmet in hand, taking it. Daboll’s face grew red as he screamed at the reserve offensive lineman.

“I wear my emotions on my sleeve,” Daboll said. “I’ve told Jack that. I talk to my players all the time or my coaches, there’s some things I’d like to help but I can’t help sometimes. Probably how I was raised.

“I’ll even get that way with myself, I talk to myself, thinking when I make a [dumb] decision or do something that I shouldn’t have done. I don’t think about it, it just happens naturally. We’re in a critical situation in a game, fourth-and-1, we’re gonna go for it. I understand mistakes happen and I got a lot of confidence in Jack, just like I do with all the other players. At that particular time I just — not happy, and whatever I say, I say. And then I think I apologize later.”

This was not premeditated in any way.

“I don’t pretend to — whatever I’m feeling, I do,” Daboll said.

In this case, Daboll once he calmed down made sure to circle back and check in with Anderson.

“It’s a relationship-driven business,” Daboll said. “Look, I’ve made plenty of mistakes and I’m madder at myself. I understand that got caught on camera. Do I like it? No. Are there times when I say ‘Man, I wish I was a little more laid back?’ Probably. Again, that’s me.”

This is not the first time a Daboll sideline rant attracted attention. He angrily barked at Daniel Jones after his quarterback threw an interception in the season opener in Nashville. The Giants went on to upset the Titans, 21-20.

Daboll has the Giants at 7-2 and through nine games is one of the leading candidates for the NFL’s Coach of the Year award.
