You hear it all the time in MMA. Such-and-such team brought so-and-so in as a training partner or a coach, and now everything is better. Not that they ever admitted that anything was bad before. Not that anyone has ever had anything less than the best training camp ever, which whipped them into the best shape of their lives. It’s just that, thanks to this one person, night has become day. Everything is different now, and every change is for the better.
