Hot take here, but I feel strongly about this so I'll say it.
Saya's white belt reign is 100x better than Tam's white belt reign. I'd even go as far as saying Saya's reign is in the top tier of all white belt reigns in Stardom history. And this is coming from a guy who honestly doesn't really like Saya. I honestly dreaded her reign because I felt like Saya's reign was going to be a lesser version of Tam's reign (which I thought was really bad). I thought it would be too soon for Saya to shoulder the burden of being a top champion, but Saya has continuously blown me away with nearly every defense she's made.
