I'd add a 4th way, any team can improve by simply putting forth the effort. If your stuck in the middle of the pack or bottom and don't like it, do something about it practice, hire a coach, etc...
You don't deserve to be competitive with the best if you don't put for the effort. The better bowlers are the better bowlers for a reason, they've worked and improved their game. If you won't make the commitment to improve, or become better, you don't deserve better.
