Okay, let me draw it out in pictures so it's perfectly clear.
Breeland Speaks in his first couple of seasons had a high TFL/sack ratio. From what I saw, he was very good at penetrating in the run game but needed work on his pass rush.
In his final season, they moved him around the line and he broke out. However, even in his final season, he played as a DOWN lineman. I used the term "hand in the dirt" as a descriptor, let me change that to "heads up right on a lineman". In other words, he was used to playing in a box and being engaged at the point of attack, beating linemen with strength and leverage.
He came to the Chiefs and the first thing they did was move him to OLB, where he no longer had "his hand in the dirt". Again, let me change the descriptor - they asked him to PLAY IN SPACE. They were expecting him to play with more speed and changing the way he could use his leverage because he had to close space between him and the lineman.
You're confusing my criticism of HOW the Chiefs used him to rush the passer as an indictment of his ability TO rush the passer. I never said he couldn't rush the passer and you completely read something into my statements I did not say.
Is it clear now?
