Bostic is a very patient player, will sit in the zone in pass coverage and will not over-commit to a play too often. He has very good footwork and if he does commit too quickly, he has a good change of direction to recover and make a play on the ball. On pass rush/blitz, Bostic has good initial quickness and the speed to get the corner and pressure the quarterback and make a play. He is a sound tackler, who uses good form most of the time. He uses his hands well to take on and stay free from OL blocks on the 2nd level, which enables him to consistently make tackles on runs at him.
While he displays good short area quickness, Bostic has not shown the explosive closing ability to make big, impact plays. At times he does not follow through on tackle after making initial contact, which allows ball carrier to break his tackle. He lacks the top end speed to run with TE down the seam and to pickup and stay with RB on "wheel" route down the sideline. Being tight in the hips hinders his ability to adjust quickly when receiver crosses his face. When he does not stay free from OL blocker and they get ahold of him, he lacks the strength to consistently anchor and can be ridden out of the play.
Bostic is a guy who possesses the athleticism, quickness and reaction to become a contributor in the NFL, although I do not see him as a starting LB. He gets moving at the snap quickly, has patience and reacts well to the play. He will not over-commit, will stand his ground and has the quickness to make the play in a small area. However, I would like to see him explode to the play better. He needs to finish plays better when he gets close them. He can change direction okay when he anticipates having to, but when he gets faked he is slow to change directions and lacks the burst to recover and get back into the play. Bostic lacks the playing speed to make plays consistently outside of the OT box - Basically, he can be productive in a small area. While he has quick hands and uses them well to stay free from OL blocks, he lacks great strength and can be ridden out of the play if the OL can lock up on him. Overall, Bostic is worthy of a late round pick as I believe he can challenge to make a roster as a backup linebacker and special teams player. However, he is not someone I believe can be a starter and will struggle to carve out a long NFL career.
