There are backups on every team in America, at every level. I would imagine a vast majority of them want to play more than they do. I would also imagine some of them would label theirs as a "bad experience"
A lot of people these days point fingers and make excuses as opposed to out working their competition. Most of those people will quickly tell you theirs is a "bad experience",
Your mileage will vary. I would say: you create your own luck. Life is what you make it. Take your best shot and own it. Those are cliches for a reason.
