Standing 6-foot-2 and weighing 215 pounds, Cantu is smaller than Sorensen, but he is more mobile. He can be effective from the pocket or in the open field.
"Different skill-set," Southern Utah coach Ed Lamb said. "Brad had tremendous confidence in his arm. He played like a big man. He was not afraid to stand in and take a hit waiting for that split-second when he could rifle the ball in."
On the other hand, Cantu "doesn't have a cannon for an arm. He wants to make the right read and he wants to get rid of the ball. He's not into taking hits.
"I don't think we'll have as many late-in-the-play completions as we did when Brad was here. But we'll have fewer sacks than we did a year ago, too."
Redshirt freshman Christian Taele and true freshmen Raysean Martin and Toa Afatasi headline the rebuilt group of running backs who will also be a key to SUU's success on offense.
"They are inexperienced, but we're very excited about them," Lamb said. "They can do a lot of different things. They give us a lot of versatility. We hope they can have some success early and gain a little confidence."
South Alabama, 2-11 last season, returns seven starters on offense including senior quarterback Ross Metheney.
