DRAFT TRACKER 2015

Winston is a big, highly competitive pocket passer who played in a pro-style offense and showed an ability to anticipate throwing windows, scan the entire field and make the NFL throws. His wind-up delivery and marginal mobility outside the pocket are reminiscent of Byron Leftwich, but his arm talent and issues with decision making are more in line with Eli Manning's. Winston's football potential is clearer than so-called "system" or "one-read" quarterbacks, but every stone must be overturned in an attempt to piece together a predictive character profile on Winston. Winston's supreme confidence might be considered arrogance by some, but even that trait will be alluring to teams who need to find a franchise quarterback.

Scheme-based quarterback who will face the same challenges that several quarterbacks before him have faced in terms of learning how to read defenses and go through progressions. The tape was less kind to Mariota than expected, but his size, athleticism and consistency of football character throughout his career are necessary traits in becoming a good-to-great quarterback. Mariota's ability to create outside the pocket will help win games here and there and buy him time as he plies his craft. However, to reach his potential and match the play with the traits, he must develop more poise and feel in the pocket and improve his field vision. Mariota is no lock to be a great NFL quarterback, but his floor is much higher than any of the quarterbacks drafted in 2014.

Hundley flashes athleticism and talent, but his basic quarterbacking issues will take time to improve. In 2014, more than 54 percent of his pass attempts were from six yards and in, including 29 percent from behind the line of scrimmage, which is nothing like an NFL offense. Hundley is a "flash" prospect who shows the physical tools to be a starter, but his internal clock and issues with reads and progressions must be improved to give him a shot at becoming a decent NFL starter.

Grayson went from fringe draft prospect to clearly on the draft board with a strong 2014 season. Despite average arm talent, he uses good lower-body mechanics to generate velocity and his touch and accuracy on deep throws is eye-opening. Grayson needs more tape work to help improve his decision-making, but his size, production and growth at the position have ticked the requisite draft boxes to make him an intriguing mid-round prospect.

NFL evaluators felt like Petty's senior season was disappointing, but those same evaluators love his size, leadership and intangibles. He needs a year or two of practice time and camp work to learn how to get through his progressions, but has the intelligence to do that. Petty must have a structured offense that won't ask him to make plays outside of the pocket.

Intriguing conversion prospect who is moving from quarterback to cornerback in an effort to make it in the NFL. It will take time for Marshall to go from a position of decision-making, patience and processing to one of frenetic energy and high-end athleticism. Marshall flashed at cornerback during Senior Bowl practices and his size will interest NFL teams, but his top-end speed and individual workouts will determine whether he's an NFL cornerback or a name-brand former college quarterback.

Tall, rhythm thrower who shows an ability to play with confidence and accuracy when used as a game manager within an offense featuring a strong rushing attack. Mannion needs plays to stay on schedule or his confidence becomes shaky and the turnovers start rolling in. Mannion lacks arm talent to carry an offense, but has enough ability to become a capable backup.

An undersized, move quarterback who can make plays outside of the pocket. Has enough arm to threaten defenses over the top. Though up and down at times, Sims has demonstrated enough potential to warrant a look as an NFL backup in a draft class sorely lacking in quarterback prospects.

Lanky "system quarterback" lacking a strong arm and an ability to create plays outside of the pocket. Halliday shows an adequate level of football intelligence and has enough accuracy to warrant a draft pick. One positive is that he has clearly improved over the last two seasons and might continue on the same track once he works into an NFL system. A role as a backup might be his ceiling.

Has NFL size and NFL intangibles but might not possess the necessary physical traits to project into a starter's role in the NFL. His competitiveness, intelligence and production will matter more to teams that are less reliant on traits-based quarterbacks. Might be looking at a career as a quality backup.

Heinicke has the ball placement and accuracy of an NFL backup when he's protected and dealing, but his small stature combined with his inability to drive the ball and make NFL throws could be hard to overcome once he gets into an NFL camp. Heinicke must play in a timing-based system to have a chance of being on an NFL roster.

Productive run-pass quarterback who was forced to carry a substantial percentage of the offensive success on his shoulders. His confidence and accuracy dipped in 2014 and he lacks the poise and arm to become a starter in the league. He's a willing learner and has a chance to be a third quarterback with "package" potential thanks to his toughness as a runner.

Has the leadership, toughness and intelligence, but lacks the height, arm and accuracy to rate as anything more than a third quarterback in the league.

A game-managing pocket passer with arm strength that is below the desired NFL level. Must play in timing- based offense. Mason displays the football intelligence, accuracy and poise worthy of an NFL camp. Must prove his intangibles can overcome his lack of arm.

One-year starter in the SEC with adequate size. Poor footwork and substantial accuracy and ball placement issues have him tabbed as a draft reject on several draft boards, according to scouts.
