So when I try to make plays- I see some differences

Like for offensive linemen, there is a pass block option for your line and then a pass block tackle/guard/center. What's the difference

Same on defense

you have rush and blitz as options- what's the difference?

Some of it is legacy to cover all of the plays we've done and the actions that expanded... you can pretty much use any of the pass block... they all work the same.

Rush and blitz are pretty much the same... but a rush is used by DT/DL and the blitz is used by LB and DB.
