Daniel Dubois has cut off the ties with Don Charles and has now become Tony Sims, adding another coach to a growing list. At the age of 27, he is in his fourth corner head in less than five years, which tells you a lot about where the actual instability is.
His last crack sack comes from his excessive Oleksandr Usyk in Wembley last July. The Ukrainians finished their matters in five rounds, stripping Dubois of their IBF title and leaving more questions than answers. And when the talk of Fight Week is about his family that hosts a party instead of crunchy Sparring sessions, it is not difficult to see why critics continue to seek.
The Bon-Go-Round goes like this: Shane McGuigan, Martin Bowers, Don Charles and now Tony Sims. Four trainers in an eight -year career, but the true statistics have been four trainers since 2020. Coaches changing fighters often rarely shout “coherence”. The explanation is always the same: “a new chapter” or “different energy”, but the problems are shown on the night of struggle, without change.
Tony Sims has a pedigree. It has been around the blog, brought Anthony Joshua an IBF title and directed the fighters who need to reconstruct. But here is the turn: Sims usually works with fighters in the Matchs room, while Dubois is still a man in Queensberry. It is not a natural marriage and it may not last long.
Charles did not directly chair a descent. Under him, Dubois defeated Jarrell Miller, Filip Hrgovic and Anthony Joshua successively, possibly the best career in his career. He even defended the IBF strap by stopping Joshua in Wembley. But all that goodwill was erased after the resale with Usyk, where Dubois folded again under elite pressure.
Now Charles is out, Sims is inside and the story is familiar. A fighter blames the corner, not in the mirror. Sims will be successful where three others failed? Possibly. But if the story is a guide, Dubois will hunt for coach number five before time.
