regardless of the fact that you are a hard hitter, you need agility/vision just as much as you need speed. You've been training strength/tackling . . . which is a bit of an issue. Take speed to 73 while you train agi/vision from now on, 68 if you get agi/vision up to 30ish each fast enough (I like 33 but no one number is super important). Once speed gets there then cap agility/vision to at least 61. Then worry about strength/tackling.
