Here's a look at what some draft experts have had to say about Bostic leading up to the draft.
Per Bostic's NFL.com profile:
Bostic is an absolute hammer in the middle of the Gators defense, especially against the run. He fights to take out blockers and to accomplish his assignment, but when he attacks with his shoulder Bostic fails to make a play on the football.. Even though he’s not as tall as some coaches would like, his production (he led the Gators with 94 tackles as a junior), onfield attitude and instincts for the ball make him a potential mid-round pick and gives him a chance to eventually earn a starting job at the next level.
From Bleacher Report's Sigmund Bloom:
Bostic seems to fit best in a 3-4 defense as a two-down ILB where his limited range won't hurt his team. He can fit at MLB in a 4-3, but it's not his optimal role in a pass-happy league. He'll be an instant contributor on special teams and a great addition to any team's culture. His instincts and toughness give him a chance to be more, but he'll have to overcome a lack of a great tools.
National Football Post's Russ Lande had this to say about Bostic's abilities:
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. 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.
And per Rob Rang of CBS Sports:
Compares to David Hawthorne, ILB, New Orleans Saints, Just as "The Heater" has done for the Saints and previously the Seattle Seahawks, Bostic will make a club as an effective run-stuffing middle linebacker despite a lack of top-notch speed.
