The best undrafted free agent in this class may end up being Davon Coleman from Arizona State. Coleman had 8.5 sacks and 15 tackles for loss his senior year according to Sports-Reference.com—almost unheard of production for a defensive tackle, let alone an undrafted one.
A major reason why Coleman went undrafted could be because he played on a stacked defensive line. Coleman played next to highly-rated players Will Sutton and Carl Bradford. After thoroughly studying Arizona State game film, it showed that that was truly not the case.
Coleman displayed incredible strength, an adequate first step and a surprisingly developed pass-rush repertoire. Coleman flashed any time you turned on ASU tape. Coleman was at times the most disruptive player on the defensive line.
He is not without his faults, however. Coleman has a tendency, like most college defensive linemen, to play very high. This will not cut it in the NFL. Coleman sometimes has too many wasted movements when attempting to rush the passer.
Thus far, Coleman has had a great offseason by all accounts. He has even received some snaps with the first-team defense.
One of the best aspects of Coleman is that he has the versatility to play the 1- or 3-technique along with strong-side defense end. When you watch film of Coleman, you see him line up at every defensive line position and provide disruption at each of them.
Coleman will likely get most of his snaps at the 3-technique position, where he can utilize his first step and strength the best.
At training camp, expect Coleman to further prove that he should have been drafted and make a serious impact while playing with the second-team defense. Look for Coleman to battle with Travis Frederick and give him all he can handle.
Coleman should cement himself as an important aspect of the Cowboys' defensive line rotation.
