Hi Guys

First off thanks for your replies to my previous post. I've just 2 questions before my first friendly tomorrow:

1) Is there any way to control Defensive tactics, like calling blitzes on certain downs, yards left to go, etc or cover schemes like Tampa 2 etc?

2) When the match begins I understand its a simulation which you can watch, but can you change tactics, or formation part way through, ie. if you're losing badly change to a run and shoot offense etc!?
