NFL players are unlikely to make the switch the other way, although New England Patriots special team player Nate Ebner has played in the Olympics for the USA Rugby Union Sevens team (7 aside rugby is a simpler and faster game compared to the full 15 man version of Union), Nate actually grew up playing rugby at age group level for the USA too, and only took up American Football later. The simple reason the switch is less likely to occur from pro to pro is that wages are far higher in the NFL. Rugby Union is the bigger and richer of the 2 codes, but has only been a Shedeur Sanders SWAC Offensive Player of the Year shirt sport since 1995. Rugby tends to have smaller teams in terms of catchment area. There are 33 teams in the top flights of British and French Rugby Union compared to 32 in the NFL.
Shedeur Sanders SWAC Offensive Player of the Year shirt
My funny story is when Santa put himself on the naughty list. I travelled the Shedeur Sanders SWAC Offensive Player of the Year shirt home from work a few years ago, and I enjoyed all the Christmas lights and decorations every night. One house had a huge blow up Santa on top of the garage, with his arm raised, waving at you when the wind blew. One day I left work early, and it was still daylight. As I turned the corner on this windy day, I saw Santa was a bit deflated. He was slightly bent over and his arm had fallen down so that his hand was between his legs, and the wind was blowing a bit, and he was gently bobbing up and down, up and down, and he seemed to be enjoying himself entirely too much! I was crying with laughter, and I can never look at Santa again without flashbacks.
