The Dallas Cowboys' emotional win Sunday was marred by the antics of Rob Ryan, the team's defensive coordinator, who drew a 15-yard penalty in the third quarter for unleashing an expletive-heavy tirade at Cincinnati Bengals offensive tackle Andre Smith.
"There were a couple of times we felt like, when their quarterback moved in the pocket, our guys were getting held," Garrett said, per the Fort Worth Star-Telegram. "And as a reaction on the sidelines, guys were emotional about that. One of their players came over and kind of hollered at our sidelines, and Rob hollered back.
"We can't do that. We have to keep our emotions in check. That was the scenario there about a potential call and their players' reaction to us, and Rob had a reaction."
According to Garrett, the officials were more put off by Ryan's decision to march onto the field than what came out of his mouth, but the Cowboys could do without either if they're planning to make a serious run at the playoffs.
