I implied that they would be more aggressive at going for the ball when I saw this:
I take it they would be more aggressive in getting back to get the ball instead of the defender, so they'll be more aggressive in general. Plus how is that a bad thing like the article implies?
If I were to guess, it would be based on situation and they'll be more aggressive to get the first down on 3rd downs. Like you said most plays are designed for players to run the route in a specific way and they should be run that way.
