#6 Will Ospreay
Given that Ospreay is only 24 years old, there is a chance that WWE will not bring him in for a while yet, allowing him to mature on the independent scene away from the critical eyes of a WWE audience. However, it's quite obvious that if Ospreay was told he'd be on Monday Night RAW tomorrow, he'd be ready.
Ospreay has learned quickly since making his in-ring debut in 2012 and has become one of the world's premier high-fliers already. His match with Ricochet at 2016's Best of the Super Juniors tournament - a prestigious tournament that Ospreay would go on to win - ensured that he would become the talk of the wrestling world, and the buzz that has surrounded him has not died, despite being rather underutilised in NJPW of late.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
Having spent most of his career in British promotions, the Essex-born Ospreay would benefit from more forays into an ROH ring, where he has worked before, so as to become more accustomed to American wrestling audience.
Ospreay could easily jump straight into NXT and impress straight away, but once he has a couple of years more experience under his belt, he'll be even better equipped to make a name for himself under the watchful eyes of Vince McMahon and Triple H.
