Reminds me more of the front-row edition of Paul Gallen because of his build. You don't need to be tall to make good metres up the middle... if anything, a little ball of muscle has a lower centre of gravity and can be extremely difficult to tackle. He's certainly built like a brick shithouse from what I've seen.
You're right, though... you never know how a junior will go when they step up to the big league. There are players that are more likely than others, and I'd put Taylor in that category from what I've seen - but you never know.
That's a good call actually. But Gallen has subtleties and skills to his game too. Not sure I've ever seen Taylor pass the ball, but he does make strong carries and plenty of them, and his low centre of gravity almost seems to help him not hinder him. I rate him as a player, but I doubt he will burst onto the scene and make waves. More likely to be a solid bench prop with good consistent stats.
