President Donald Trump and the Republicans in Congress have moved to repeal the Affordable Care Act — more commonly called Obamacare — and replace it with … something.

This is of concern to the millions who rely on the ACA for health insurance, which pays part or most of their medical bills covering the services/operations/consultations/prescriptions that keep them alive.

It’s also an issue for the NFL Players Association:

Obamacare forbid insurance providers from declining to cover people due to pre-existing conditions. It also protects consumers against exorbitant premiums based on a pre-existing condition.

You may think ex-NFL players should be able to easily afford insurance, but most of them last only a few years in the league and don’t net nearly enough to cover expenses for more than a few years of retirement (80 percent of ex-players go broke, according to some estimates). But even those players — thanks to high school and college in addition to their time in the pros — will deal with knees that need to be looked at or shoulders that always ache or a brain that doesn’t quite work the way it once did.
