STRENGTHS - Barker has good bulk for an interior lineman and appears larger than his listed weight. He demonstrates very good quickness off the snap, which allows him to set quickly before defenders can get into him. He demonstrates the foot quickness needed to block at the second level. In pass pro he is quick to recognize stunts and shows the ability to redirect and recover.
WEAKNESSES - Barker does not show strong lower body flexibility, as he tends to bend at his waist instead of his knees. This causes him to play off balance and fall of blocks early, both in pass pro and against the run. On run plays he struggles to get a consistent push off the LOS and when pass blocking he does not play with a wide enough base, causing him to be jolted back by physical bull rushes. While he has the foot quickness to get out on pulls he tends to be sluggish down the LOS and slow to locate and attack his targets.
SUMMARY - Barker looks the part of an NFL lineman, but will struggle to make a final roster because of his lower body stiffness. He consistently bends at the waist and gets his weight too far forward, which causes him to lose his balance and fall off blocks quickly. Although he is quick out of his stance and into his set, he isn't physical at the POA and struggles to get a push off the LOS. He also struggles to hold the POA in pass pro, and struggles to maintain against moving targets. He is worth a late day three selection because he has the body type to play at the next level, but he will need to get stronger at the POA as well as improve his flexibility if he is to maintain a long term career at the NFL level.
