If they have different levels of difficulty, or let you turn it off it will be ok.
If not then it's completely ridiculous. Being an NFL head coach is hard as hell. Most of those guys get 4 hours of sleep every night and are some of the most stressed out people around. I'm not saying they should make it THAT difficult to the point of your hair turning gray, but to have good FA's come to you or a player suddenly become good because you're about to be fired it the stupid stuff that makes EA who they are.
