What do you think of this team?

[Cat Harrison]

If you trust your GK, that is to say, he makes saves for you sometimes, get good ratings and you have decent D, (which it looks like you might) I think keep him, and invest in other position players. Maybe get a Free Agent or cheap backup for him later.

As for the stadium you want a stadium big enuff for the most fans, to get $ and bonus possession.
