"He refused fights."
"Some of that was matches falling through," oh, so you mean the fights he was refusing fell through? That's weird how he wasn't taking fights only for those fights he apparently didn't take to fall through.
Colby was willing to fight NO ONE. Leon didn't want to fight an unranked guy that he still agreed to fight 3 times.
Leon was going to be in 2 title eliminators that got canceled. He already had a top 5 win sheet the first one and could have got the shot back then, but the rest of the bookings were 'stay busy' stuff or attempts to popularize his name. He didn't even get the shot for beating Nate like everyone bullshits, he was going to fight Jorge next, but Jorge pulled out, just like Nate did he first time, and just like Khamzat did to him twice.
It's nowhere near the same, and even if it was, there's STILL a better contender than both of them were who is getting screwed right now
