Scott Adkins vs. Gary Daniels
This is a fight that MUST happen. Gary Daniels was to the 90's what Adkins is in this current era.
Most of the other guys they want to pair off for Adkins are either too old (Van Damme), too small for him to look like he's in for a challenge (like Donnie Yen or Tony Jaa) or basically just can't keep up with all his crazy athletics (Like Michael Jai White).
Though Gary Daniels is not on the level of athleticism of Adkins (although Dacascos can probably try to keep up), he still has some of the sweetest moves in his era and has extreme flexibility despite his ripped physique.
This fight needs to happen and it needs to happen now before Daniels gets too old.
Scott if you're reading this... well please consider it.
