Ospreay has had more standout classics than Terry Funk has. This is just a simple fact. Other than his matches against Ric Flair, what singles match from Terry Funk's catalog stands out?... There aren't any that come to mind.
I've seen all of the most historically significant ones. Most of Terry Funk's best matches involved blood or a stipulation. Ospreay doesn't need to cut corners with weapons or gimmicks.
You might personally think Ospreay is the worst wrestler in the world, but just because you don't appreciate something doesn't diminish its value. Look at Cagematch. Ospreay has over 200 matches rated 8 or higher, and he's only been active since 2011. Terry can't compete.
