I believe that your squad is good enough to compete in this league. The biggest tip that I can give you is to take care of your enthusiasm and game shape. The last 3 seasons or so I've noticed that Miller is playing too many minutes and your team is suffering for it. Right now, 2 of your best guys have a GS of average...and at this level...that wont get it done against the better teams in our L. Keep Miller and your key guys at 60-65 minutes a week and see what the difference is. You'd be surprised at the difference between a strong or proficient GS versus average and respectable.
