He played some running back in high school and was recruited by SEC powers like South Carolina and
Georgia at the position, but chose UCLA and the Pac-12 because of his preference to play linebacker.
And he has been a dominant force at the position in only his first season as a Bruin, with 63 tackles (11 for loss), one interception and team-high nine pass broken up. Jack has helped make the UCLA front seven one of the toughest in the Pac-12 and has also been used in pass coverage.
It seems there's nothing Jack can't do.
Against Arizona, he ran for 120 yards and broke several tackles as he displayed speed and tenacity as a runner on a 66-yard touchdown burst.
"It was just situations where I had an alley or a crease based off of the blocking scheme," Jack said. "The way the situation was set up was perfect, all I really had to do was run."
