Guerrero would be an okay choice, but not really an ideal one because he was already knocked out by 40-year-old Grady Brewer last year in June, and that kind of takes the interest out of watching him fight Golovkin. Guerrero has won his last four fights since the defeat to Brewer, albeit he’s faced 2nd tier opposition.
Golovkin doesn’t have a lot of good options right now because the middleweight division is so dead right now and lacking in talent. There’s a small handful of fighters that would be interesting for Golovkin but it’s doubtful that any of them will be available to fight him or would be interested in facing him. He hits too hard and he doesn’t have a big name like Sergio Martinez or Julio Cesar Chavez Jr. yet.
In his last fight, Golovkin destroyed Grzegorz Proksa by a 5th round knockout last September. That fight really surprised a lot of boxing fans and writers because it was thought that Proksa would give Golovkin some problems and might even be good enough to beat him. However, it was totally one-sided with Golovkin knocking Proksa down three times before the fight was eventually halted.
Here are the worthwhile top contenders that Golovkin has to pool from for his next fight:
Golovkin would be lucky if he could get even one of those fighters to agree to face him, because it’s very unlikely that any of them will be not scheduled for a fight or interested in facing him.
