Does a nice job extending his long arms into blocks, but because of his high pad level, he struggles to generate much push on his bull rush and lacks the lateral suddenness to effectively slip blocks in the pass game when engaged. However, does have the athleticism to be somewhat effective when asked to keep himself clean on the stunt, drop his pad level and drive his way into the backfield.
Now, he does play with better leverage against the run game and does a much better job sitting into his stance, extending his arms and holding the point of attack. He's still an above-average athlete who has some range on the move. But, he still isn't real instinctive when asked to find the football. He will routinely take false steps trying to find the football, virtually sealing himself from the play.
Impression: Displays some natural athleticism and range for the position and his added weight has made him a much better player vs. the run. Isn't a natural pass rusher, but should get some looks as a potential five-technique guy at the next level."
Positive: Deceptively strong interior lineman with the ability to overpower opponents. Plays with leverage, drives up the field, and flashes power on the inside. Consistently displays the ability to hold the point. Fires off the snap with a solid first step, changes directions well, and makes plays in the box. Chases the action hard.
Negative: Must do a better job using his hands to protect himself and develop moves to get off blocks. Average skills in pursuit.
Analysis: Lumpkin is a workman-type lineman in the middle of the field who does the little things well to allow teammates to make plays. He lacks classic size yet should get consideration on the inside of a four-man line."
