Can someone please help me.

I think someone already touched on this but it bears repeating; the game isn't great at being consistent, has bugs and can just give the other players huge plays despite your best efforts. Since the last update it's worse, so stick with the plays you know well and coverages that suit your players more than your style. Players that give boosts have become clutch, especially at O line(red tornado for example). If you get into a bad losing streak shut the game down and restart, works 90% of the time
