When I was younger I used to play at a well-known football academy. Some of the better players stayed on, and one of them (easily the best player in our cohort) signed a professional deal. He was 10x better than me, a player that was probably considered pretty good by normal standards.
Compared to pros he was nothing. He never played a game, had his contract terminated, and he eventually found his level in the 9th tier of English football (lower regional leagues).
Age aside, Ryan Reynolds would look hilarious out there. At his fittest, I still think he’d almost definitely get injured trying to go up against a pro defender. Similar to the sort of smurfing videos you see of pro fighters destroying a local gym in disguise, the difference between even someone at National league or League 2 level to a “good” footballer is crazy.
