This season, Duffey threw for 2,840 yards, 18 touchdowns and five interceptions in 10 games. He completed 65% of his passes and also ran for 212 yards and a score.
As a sophomore in 2018, he rushed for 369 yards, becoming the first quarterback to lead Texas Tech in rushing since 1973. He threw for 1,221 yards in eight games, including three starts.
Since he is a graduate transfer, Duffey will be eligible to play for the Green Wave in the 2020 season.
