Pinion and McCullough have worked together since they both arrived in Atlanta in 2022. Apart from the final three games last season, when Koo was on injured reserve with a hip injury and Riley Patterson was signed as a temporary fix, they've only ever known Koo as their kicker.
Patterson made four of his seven field-goal attempts but never had a zero-miss game.
That Romo was perfect in his first live game with Pinion and McCullough is noteworthy, especially considering the expedited timeline and the eventual quantity.
"It speaks to the pros that they're after," said Falcons offensive lineman Chris Lindstrom, who does field-goal coverage. "(Special teams coordinator Marquice Williams) does such a great job with them. So much of the NFL is predicated on operation time. Snap, hold, kick. I don't know the number, but those guys do. It has to be off in a certain amount of operation time to beat, a lot of the time, the defender that's rushing outside the wing. You're barely blocking that guy. You're saying operation time is going to beat that guy. So, obviously the fact that they were able to do that with a short week together was impressive."
Romo's first four kicks were within 40 yards, so not too difficult. But his fifth and final was a 54-yarder, just one yard short of his career-long distance.
The Falcons don't necessarily have to make an immediate decision about their long-term kicker. Romo has reverted back to the practice squad, and Atlanta can elevate him another two times before he must be on the active roster in order to play again. However, while on the practice squad, Romo can be signed by another team to its active roster. So, there is a slight risk in keeping both Koo and Romo in their current positions.
"There is about a 90% chance that Romo is our kicker for next week," Falcons head coach Raheem Morris said. "There's no doubt about that. I wouldn't even sit here and ask like it's an open competition because the guy just went 5-for-5. You want to see it again. You want to see it in a different atmosphere. You want to see those all things. He did a heck of a job, and I want him to go out there and do it again."
