I agree. Also on Wright, I love that he can slot in from fullback and be the second playmaker and be a vocal voice to help game management especially in the back 3. This is really his point of difference. No other options really have his playmaking ability (he used to play 10 I believe).
But his deficiencies under the high ball, his error rate, and general decision-making, just doesn't sit well at fullback. You want a cool, calm, collected, low-error, strong decision-maker - this is where a player like Kellaway shines.
