Mosley was relatively lightly recruited out of high school but wound up signing on with Coffeyville [Kansas] Community College, one of the top junior college programs in the country. He initially lined up at defensive end before making the switch to tight end (his primary position in high school). He signed with Auburn as a tight end.
However, upon signing with Auburn, the Tigers' coaching staff asked him to gain weight and move to the offensive line. Quickly taking to the position, Mosley surprisingly leapt another JUCO-transfer Roszell Gayden, who had garnered higher praise upon signing. Mosley saw action in 14 games in his first season in the program, starting the final 11 contests (including the BCS Championship) consecutively.
The mobility of Cam Newton may have kept some defenses from sending speed rushers his way, so it will be interesting to see how well he fairs now that Newton is a Carolina Panthers. What is very clear is this -- while raw, Moseley maintained good initial quickness despite adding weight and stepped into the country's toughest conference and played well immediately. Considering his long arms and surprisingly powerful base, he'll surely be one of the more heavily scouted offensive linemen in the SEC this year.
Pass Blocking: Eases out of his stance to "catch" the pass rusher as he attacks the line of scrimmage. Plays with good knee bend and above average lateral agility to remain square to the pass rusher. Gets a good initial punch on the defender to dictate the action and has the long, strong arms to control his opponent. Typically plays with good hand placement, though he did get himself in trouble, at times, when his hands got too low, leading to some trouble with swim moves. Cognizant blocker who reacted well (despite his limited experience) to stunts and unexpected blitzes. Seems to enjoy the physical nature of the position and looks to help his teammates when teams dropped their defensive ends in an attempt to confuse the quarterback.
Run Blocking: Gains a good push off the snap due to leverage and surprising leg drive. Quick enough to turn and seal off defenders to create an edge. A bit inconsistent with his hand placement when run blocking, as well, leading to some slipped blocks.
Pulling/Trapping: Above average quickness and mobility when blocking on the move. Effectively sells the trap block, allowing defenders past him, before turning and sealing them off from the ball-carrier. Not asked to pull, but occasionally released to block at the second level, showing the ability to hit the moving target.
Initial Quickness: Good initial quickness off the snap when easing into pass protection, as well as when run blocking. Quickly gained the advantage over his assignment, dictating the action.
DownField: Surprisingly fluid getting to and adjusting once at the second level. Was consistently able to get to quality linebackers (LSU, Alabama, South Carolina) and seal them off from the ball-carrier. Flashes some nastiness, as he'll pancake his opponent if he felt them off-balance, but more often he remained in front of the defender, effectively finishing the block.
Intangibles: Earned all-conference honors at Coffeyville as a tight end in 2009 despite only playing half the season at the position. Caught 12 passes for 229 yards and two touchdowns after making the position switch from defensive end where he recorded 35 tackles, including four tackles for loss and 1.5 sacks. Earned significantly more attention from top teams as a JUCO prospect and turned down interest from Florida State and Ole Miss to sign with Auburn... Teammates and coaches at Auburn raved about his preparation and work ethic as he won the starting right tackle job in his first year in the program..."
Plays from a two-point stance, but is a decent bender for his size at times, can keep his base down off the ball well enough in the run game and create leverage for himself at the point. However, will get sloppy with his technique and bend more at the waist when he knows he has to reach speed off the edge in the pass game.
Wastes some motion on his punch and will wind up into contact, allowing defenders to initially get into his chest. However, he displays a strong upper body and when he does release his hands he can jar on contact.
Exhibits the ability to get an initial push off the line in the run game, is sticky through contact and again will finish. Isn't overpowering, but can create an initial surge.
Possesses average range off the edge in pass protection. Gets overextend on his power step and swing his arms consistently in order to create momentum for himself toward the edge.
Needs to do a better job keeping his hands in front of him to protect his chest as he routinely gives up inside hand placement and at times will get jacked on contact because of it. Is gritty though once he gets a hold of you and is tough to disengage from. Demonstrates fair natural balance and can anchor through the play.
Gets too wide with his footwork on his initial power step, but keeps working his feet through contact and on tape shows the natural footwork to eventually hold his own when asked to develop a kick slide in the NFL. Understands angles, knows his limitations and loves to compete.
Impression: A tough kid who plays hard, likes to finish and understands angles in the pass game. Has some upside down the line coming from a JUCO program in 2010, but as of now looks like a roster guy in year one who could fight for playing time down the line. Reminds me some of former UVA OT Will Barker."
Plays on his feet with good balance and urgency and seeks to get into blocks quickly.
Technique is still a work in progress and will open the gate in pass protection.
Must continue to improve functional playing strength.
Very good work ethic — the game is important to him.
His ability to play on both sides and potentially contribute anywhere on the line is a plus and minimally could allow him to develop as a versatile, swing backup.
Is only a one-year starter and has upside to be groomed. Has eventual starter potential."
Athletic player with long arms and light feet; also has very good functional strength; physical run blocker, but isn’t all that technically polished; same as a pass blocker as he has upside tools, but is very raw."
