I'm probably not going to watch the video to be honest TS. Pretty clear this is just a shameless self promotion and you probably don't care what any of us have to say.
But I've been riding the Spence train for a couple of years. And IMO, he's going to drive that train right over Brook. It's hard to say really because Spence hasn't faced someone that boxes as well as Brook. But given Brook just jumped weight and took a beating, I don't think the drop back is going to be good for him.
