If you learn how to user catch deep balls are VERY easy to complete, even on Heisman. Heisman I would have a 50% chance of pulling down a deep pass on 1-1 coverage. On AA or below it goes up to 85% at least.

These are guesses.
I'm not bragging...it's just easy. I don't even allow myself to do it anymore which sucks because when my AI controlled WRs go down the field they are brain dead. The WR/DB interaction is atrocious.
