Brandon Allen, Arkansas
A three-year starter for the Razorbacks, Allen put up some pretty darn impressive numbers over the past two campaigns. During that span, he combined for a 60 percent completion rate with over 5,700 passing yards, 50 touchdowns and just 13 interceptions.
Likely a late-round option at best heading into Senior Bowl week, Allen will have an opportunity to prove himself to the 32 teams that will be down in Mobile. A pocket passer if there ever was one, Allen is going to have to show off a solid arm in order to impress scouts. That's likely going to be the primary focus of NFL teams during the week, even more so than in the game itself.
Jacoby Brissett, North Carolina State
Uber productive during a two-year stint as the Wolfpack starter, Brissett completed 60 percent of his passes with 43 passing touchdowns and 11 interceptions in 26 games. He also added nearly 900 rushing yards with nine scores on the ground.
Considered a mid-to-late round pick by scouts heading into next week, the primary focus here will be accuracy and going through his progressions. While Brissett did improve in both aspects of the game during the 2015 season, he's going to have to do a lot more to catch the attention of scouts in Mobile. That much is clear.
Jake Coker, Alabama
A starter for just one year at Bama, Coker did everything that was asked of him for an offense that was predicated on the run game. Unfortunately, that "game manager" label in college doesn't translate all too well over to the NFL level and what scouts like to hear.
Though, it's important to note that Coker has the size (6-foot-4) and arm to be considered a pro-level quarterback. One scout even had this to say during Coker's senior season with the Crimson Tide:
“He has size and a pro arm,” the scout said. “I think he can be a better pro than college quarterback.”
Lane Kiffin's offense is more pro-style than pretty much any top program out there. This is also going to work to Coker's advantage. A strong showing during practice and in the game will do a lot to put this previously unknown prospect on the front burner around the scouting community.
Jeff Driskel, Louisiana Tech
A downright failure during his time at Florida (23 touchdowns, 20 interceptions), Driskel did a solid job after transferring to Louisiana Tech prior to his senior year. He put up over 4,000 yards with 27 touchdowns and eight picks while completing nearly 63 percent of his passes.
In this, Driskel made an impression around the scouting community. However, he's going to need a strong showing here for people to forget about his disastrous three-plus years with the Gators. That's what the Senior Bowl is all about — eliminating narratives that were thrown your way during college.
Kevin Hogan, Stanford
It's hard to imagine another quarterback in this year's draft class that has fallen off the face of the scouting community since earlier in his college career. As a sophomore with Stanford back in 2012, Hogan was considered a can't-miss pro prospect. Heading into the Senior Bowl, and even after three successful seasons as the Cardinal starter, Hogan isn't considered much more than a late-round pick.
The surface-based issue here is just how little Hogan was asked to do in a run-first offense with Stanford. After all, he attempted an average of just 21 passes as a senior in 2015.
More than that, Hogan tends to struggle with accuracy, even on short-to-intermediate routes. That coupled with a prolonged throwing motion and some questionable mechanics has to be considered a red flag. Though, the Rose Bowl-winning quarterback does boast a strong arm and can make pretty much every throw on the field.
Cody Kessler, USC
One of the top recruits in the nation out of high school, Kessler started as a true sophomore in 2013. He responded by putting up a great statistical three-year career with the Trojans. During that span, Kessler completed nearly 68 percent of his passes with 10,339 yards, 88 touchdowns and 19 interceptions.
Arm strength, footwork and deep-ball accuracy are three things Kessler needs to improve on if he's going to be a legit pro quarterback. While you are dealt the hand you are dealt as it relates to arm strength, improving his footwork could help Kessler put more velocity on the ball.
The larger issue here is the mechanics. While it hasn't impacted his short-to-intermediate accuracy, both of which are really good, it could have a negative impact on his ability to beat the defense over the top. Scouts are going to want to check him out in this regard during practice week.
Dak Prescott, Mississippi State
Prescott improved every season with the Bulldogs, especially from a throwing motion and accuracy standpoint. In fact, he's coming off a senior season that saw him complete 66 percent of his passes, up nearly 10 percent from his sophomore campaign.
Prescott will need to show the ability to keep his improved mechanics when faced with pressure. This is something we saw break down multiple times throughout his career with Mississippi State. It also led to some pretty bad decisions, especially when it came to staring down his primary receiver.
In this, mental processing and the ability to progress through his initial read will be two things that scouts are going to check out in Mobile. Of course, that's in addition to what remain questionable mechanics.
Carson Wentz, North Dakota State
The highest-upside quarterback at the Senior Bowl, this small-school signal caller has caught the eye of armchair scouts around the football world over the past several months. Now potentially considered a borderline first-round pick, Wentz's ability to impress in Mobile could lock him into that positioning heading into the NFL Scouting Combine.
At 6-foot-6 and 231 pounds, Wentz has ideal size for the next level. He has ideal arm strength, shows plus-level accuracy and isn't afraid to stand in the pocket and take a hit. Those are big positives heading into Mobile. He also has a darn good pocket presence.
That said, Wentz will need to improve on the processing aspect of the game. He's often too late to make decisions, struggles getting past his primary read and needs to do a better job keeping his eyes down the field. These are generic issues for most quarterback prospects. If he's able to show improvement in these aspects during the draft process, Wentz could very well end up as a first-round pick. It all starts during Senior Bowl week.
