The problem is that though he is a good football player, he hasn't shown consistently he can hold the edge. He is more of an interior penetrator than an edge rusher. You keep saying how explosive he is and how he pursues the runners in all situations and blows through blockers in all situations. I have not seen that on any of the tape. I have yet to see tape of Joey Bosa chasing down runners or getting around the edge fast enough to bring down mobile quarterbacks, and that is not a knock on him, he's just not that kind of player. He is a great player, but he isn't a Jadeveon Clowney edge defender drawing multiple blockers every play. I am not even alone in thinking this. Notice how every Bosa comparison is to a player that played in a 3-5, and was not overly successful-Jared Allen (Bears switched to a 3-4, traded Allen to the Panthers even though they had him cheap), Mario Williams (Texas switched to a 3-4, Williams was out of place and left in FA to go to the Bills), Chris Long (was a 3-4 5-technique in college, had to shed weight to play strongside end in St. Louis).
