Senior quarterback Matt Scott played an integral role in Arizona's success on offense last season, ranking seventh nationally in yards gained.
Given how poorly the team's defense played (more on that later), he arguably was the team's most valuable player.
Fortunately for the Wildcats, the team has a variety of intriguing options to replace him in 2013. Here are the three most likely going into spring camp:
B.J. Denker (senior; 6'3", 177 lbs)
A junior college transfer last season, Denker earned the nickname "Vanilla Vick" for his proficiency as both a runner and a passer.
He seldom played but performed admirably (12-of-14, 136 yards, 2 touchdowns; 9 rushes, 46 yards, touchdown) while starting for an injured Scott in a 56-31 victory over Colorado.
He largely deferred to Carey, who amassed a conference-record 366 rushing yards.
Jesse Scroggins (junior; 6'3", 210 lbs)
Scroggins arrived at USC as a highly touted prospect yet ended up playing two seasons for El Camino College before enrolling at Arizona this spring.
More of a pure pocket passer, Scroggins offers an incredibly strong arm.
Scroggins' more conventional skill set would present yet another challenge for Rodriguez—most recently accustomed to Denard Robinson and Scott—as he caters his play-calling to the strengths of his field general.
Anu Solomon (freshman; 6'1", 205 lbs)
Sports Illustrated has predicted that Solomon, a consensus 4-star recruit out of Nevada, has the best chance of any freshman quarterback to impact his team in 2013.
His dual-threat abilities seem to make him a perfect project—and, possibly, a Week 1 contributor—in the Wildcats spread attack.
At this point, the safe bet to start in September is Denker, based on his experience in the offense and his proven versatility.
With Denker under center, the team likely would operate a run-heavy gameplan that revolves around Carey, the kind of approach Rodriguez traditionally has employed with good success.
If Carey's off-field issues and/or an injury removes him as the offensive centerpiece, Scroggins would become the more likely No. 1 option.
While his presence may mean significantly less of the read-option, Rodriguez's bread-and-butter play, Scroggins likely is already the team's best passer.
His ability to spread the field vertically would complement a receiving corps that returns the highly productive Austin Hill (1,364 yards, 11 touchdowns in 2012) and many other veterans.
Though a bright prospect, Soloman would be a poor choice to start as a true freshman.
ESPN has noted a sparse record of successful first-year college quarterbacks, and Rodriguez likely would prefer to groom a player who could become his next high-profile success story.
Unless Denker and Scroggins get hurt or show incredible incompetence through fall camp, count on Solomon to redshirt in 2013.
