These are the only ones I can think of from shadowing a small town sports pod.
Pros:
Most of your patients will not have medicare. This means less paperwork/red tape and better reimbursement. One of my pod's close friends is a Texas sports pod that does have to take medicare patients because his practice is doing so well...
You can get your name out their by working CC/track meets, marathons, etc.
Cons:
Depending on where you work and your experience, you might have to take a variety of patients just to keep your practice alive. My pod has to do this but it gives him a wide range of patients (5 year olds with warts to 100 year olds with Charcot foot) 👍
