Redshirt sophomore quarterback Dallas Sealey passed redshirt senior and incumbent starter Parker McKenzie in the starting quarterback race.

Sealey put decent numbers in his first career action this past season. He completed 60.1 percent of his passes for 824 yards, four touchdowns against three interceptions.

His biggest contribution to the Wildcat offense is his scrambling ability. He rushed for 173 yards (rushing yards include sacks in NCAA) and two touchdowns.

He also managed to avoid sacks better than McKenzie who was sacked 27 times to Sealey’s 14.

McKenzie put up All-Conference numbers in 2014, but regressed in 2015. He threw for 3,084 yards, 22 touchdowns and just nine interceptions in 2014. In 2015, he threw for just 1,855 yards, 14 touchdowns and nine interceptions in nine starts.

As was the talk of last season, not all offensive struggles came from the quarterback position. In addition to several key injuries across the board on both sides of the ball, ACU football as a whole took a step back in 2015. Collums knows what he has in McKenzie but, he decided to make the change based upon Sealey’s athleticism.

“We know we can win and play well offensively with Parker,” Collums said. “He can throw the ball and read defenses, but Dallas can make more plays with his feet. That’s the area that separates those guys.”

Sealey showed what his versatility could do against nationally ranked McNeese State. He threw for 284 yards, one touchdown and one interception against the Southland’s best defense. The Oklahoma native added 29 rushing yards and a nine-yard touchdown reception in the Wildcats’ 15-13 loss.
