what is the second best american football.league in the world

The NFL is the clear number one American football league worldwide, so the usual answer for “second best” is the Canadian Football League (CFL). The CFL is generally viewed as the strongest pro league after the NFL because it has the deepest talent pool, longest history, and highest overall competitive level among non-NFL American football leagues.

Why the CFL is usually #2

• It is the best-known professional league outside the NFL.
• It attracts many former college players and some NFL-adjacent talent.
• It has the most established national footprint after the NFL.

Important caveat

There is no single official global ranking for American football leagues, so “second best” is partly opinion-based. Some people might argue for a top European league or another pro circuit, but the CFL is the most common answer.

In practice

If you mean pro leagues only , the answer is CFL. If you mean all football ecosystems , the NFL still dominates everything else by a wide margin.

TL;DR: The CFL is generally considered the second-best American football league in the world.
