It's true that the federal gov't can't mandate vaccines because, as you say, that's prohibited for emergency use authorized vaccines. But, from the CDC site, "However, whether a state, local government, or employer, for example, may require or mandate COVID-19 vaccination is a matter of state or other applicable law."
For instance in California, the latest guidance from the Department of Fair Employment and Housing on Covid-19 vaccination policies says, "Can employers require their employees to be vaccinated? The short answer is yes, so long as the employer adheres to the requirements of the Fair Employment and Housing Act." The requirements are basically that the employer accommodate religion and medical conditions.
So, you're right, it would be difficult from a league-wide perspective, but I think most teams would be able to. Each state law would have to be checked.
