If I had a player who was going to be a scorer, there are potential strategies where it could be beneficial they are aggressive, particularly if you have depth.
Unfortunately, I got stuck with my defensive C as super aggressive, and I can't see any benefits there at all. I could have dropped training him, but it was about a year irl of training that I realized his aggression skill was really high, and at that point I didn't have the motivation to start again.
