You can't blame dephh fully for his style of calling, it's default heavy. It was coach's fault for not identifying earlier that he wasn't the right fit for this group of players.
dephh is a good caller, but not for that particular roster, I think the real issue was roles, and dephh needing to IGL from the pack, and the fact Sen are poppy even on slow plays, and dephh didn't like those executes from what I saw.
