I've watched several whole sudbury games now, and it was a case of he(Byfield) either gets a point while on the rush or the puck ends up in the corner and he loses it or gets knocked on his ass by a 5'11" defenseman while skating with his head down. My feeling is the exact opposite as you; I think he has high bust potential relative to his position. I think his size and speed will make him a player for a time, but there's very little east-west to his game, next to no sandpaper in his game for a guy that's as big as he is, and players in the NHL hit a hell of a lot harder than they do in the OHL. I think he's going to have a lot longer learning curve than any of the other guys in the top 5 this year.
I would keep him in junior for a year. But it is hilarious to me that you can be a pro Rossi guy and talk about how much stronger the players are at the next level and how hard they hit. Byfield actually has the ability to be one of those and is nowhere near physically developed. He doesn't even turn 18 for six more days.
He has elite skating on a 6'4" frame. Not good skating, elite skating... He has great hands, I have seen him pick apart teams on multiple levels. He scores a lot in transition because he easily gets into transition, this is because of how explosive he is as a skater, his first few steps are fast and his top gear is exceptional, the guys at the next level don't skate like him by and large either. There are several players like that in the NHL in terms of scoring, most of those guys get more physical over time too. He is armed with an elite shot, humongous reach. His skill set translates up, it is what you look for. The player you just kind of put out there as his floor is Athanasiou and he hasn't had near the issues you saw with Athanasiou in junior or the GTA for that matter. I think his real floor is a very good #2C. I have seen Byfield be physical by the way, I think he understands he will be penalized for that because of how he has grown up being larger than everyone. I do think his bigger years are a couple years out though. I think he is going to be a monster around age 20 or 21. I would put him back in the OHL though next year and if you're the Wings there is no penalty in doing so. I think he can develop more there.
