Should Remain in NXT #4: Oney Lorcan

The wily and skilled Oney Lorcan has some impressive accolades on his pedigree. For one, he was trained by ECW original and recognized technical wrestling master Lance "Can I be serious for a moment" Storm. Then he was further trained by WWE tag team champion and announcer Sho Funaki.
From 2008 to 2015, Lorcan plied his trade on the independent circuit. He made it as far as Evolve and Pro Wrestling Guerrilla before he was signed by the WWE. Lorcan is a worldly veteran wrestler and one of the more underrated stars under NXT contract. Does that mean he's ready for the main roster?
Why he should remain in NXT: Given Lorcan's lack of size or impressive appearance, he might struggle to be noticed on the main roster. On NXT he is valued and appreciated for who and what he is, so why would he need to make the jump to the main roster?
