Chimaev moving to light heavyweight raises concerns about advantages

Khamzat Chimaev is moving up to light heavyweight, with Jiri Prochazka suggested as the most interesting matchup given their history. The author expresses skepticism about Chimaev's chances at 205 pounds, noting he will lose his key advantages of length and physical strength against naturally bigger opponents who are all over 190 cm tall. Concerns are raised about his health given recurring cardio issues, whether from extreme weight cutting (walking around at 105-108 kg and cutting to 185), years of overtraining, or congenital problems. The analysis suggests fully adapting to the new weight class will take years and questions whether the physical toll of competing at light heavyweight while maintaining such high walking weight could worsen his systemic issues. The author warns of significant risks including potential back-to-back losses that could damage his reputation, though acknowledges fan interest in seeing him face Prochazka.
