After seeing Morales and his party off, Link went to the locker room to visit Mario, who had been knocked unconscious.
However, the guy was sulking as if he had been greatly wronged.
Link didn't bother with him anymore and then found West, asking him to recruit one or two more sparring partners who were physically fit, resilient, and had better technique.
Generally speaking, just like coaches, sparring partners play a significant role in the development process of a boxer.
Having a formidable sparring partner to spar with every day accelerates the growth speed, like John Ruiz, Oliver McCall, Larry Holmes, Lennox Lewis, all of whom had been sparring partners before entering the professional boxing ring and later became world champions.
This is a mutually beneficial process.
Mario was physically fit and strong, but the guy was a bit dumb and slow in learning, unable to keep up with Link's pace of growth or meet his needs.
