How would a top NFL player fair in a pro Rugby Union team?

Ever wondered how a top NFL player would perform in a pro Rugby Union team? It's a fascinating thought, isn't it? The athleticism, strength, and agility of NFL players would undoubtedly be beneficial. However, they would also need to adapt to Rugby's continuous play style, different tackling techniques, and ball handling skills. Overall, with some dedicated training and time, I believe an NFL player could make a successful transition to Rugby Union, but it wouldn't be an overnight process.
