Macklin is decent but I dont think he's a World beater, tbh he doesnt deserve that shot yet. I would think he should fight a higher ranked european at least before getting a Williams shot. I kind of doubt he thinks he will really get the fight. Look at the guys hes been fighting, of course he thinks he can handle it after fighting those guys. If he beats a Sturm or Sylvester, then he will be in good shape for any fight at middle he wants.
