Strengths

• Short, stumpy build so he typically wins the leverage battle. When he does so, Chapman can be tough to move, even showing the ability to handle double-teams.
• Strong tackler. Has good power in hands and can anchor, shed, and chase.
• Played with good leverage, even on the nose, despite average bulk. Hustle defender with a good bull rush inside that can close and get home when quarterbacks leave the pocket.
• Lacks the size to compete as a traditional defensive tackle and is a projection to any other position.
• Played with lean and leverage against the run, tough for one man to move (sometimes double-teams, too).

Weaknesses

• Might be limited to one-gap systems. Agility isn't a question but misses tackles when he doesn't square and break down.
• Only adequate burst off the snap even when directly over the ball, and his initial pop leaves room to be desired.
• Hands could be much more violent when trying to gain control of the block. Does not hold his ground while facing a double-team; first instinct is to roll away to make a play, which can create a large hole.
• Has limited range and is more of a run-stuffer who won't make many plays in the backfield - a mid-round, prospect who should be able to offer depth along the defensive line in any scheme.
• Isn't able to consistently shed blocks and makes plays in the hole.
