3. Will Ospreay

As soon as Will Ospreay joined CHAOS, he made a statement as the stable's most opportune chance to lead the Juniors division. In 2016 up till today, he's let that statement ring true with his performances including a title win at Wrestle Kingdom 12. Ospreay is just the kind of world traveling competitor to bring CHAOS notoriety.
Unfortunately, he's not the kind to elevate CHAOS's original motto of reviving strong style. He's hard-hitting but more in a fast-impact moves sort of way. He gives zing to the group and not the kind Jay White is really a fan of. This obviously positions him as a strong suit to keep loyal to Kazuchika Okada.
It helps that Ospreay is one of the few and first to have challenged Okada's growing ego during this past year. The two stable-mates fought while they were champions and while Okada came out the victor, he did so with a modicum of respect for his Junior division lead.
This is probably what stopped Okada from going into the deep end, had he beaten Ospreay soundly he might have completely snapped. Of course, it's Ospreay and that would be impossible since he is one of the world's best.
Ospreay sticks to his guns as a member of Rainmaker's CHAOS!
