IDEAS WORTH REMEMBERING
7 ideasDefensive game plans can blunt offense against elite pressure fighters.
Kavanagh admits he over-emphasized defending Khabib’s takedowns and survivability early, which dulled McGregor’s usual offensive sharpness and contributed to missed opportunities, especially in round three.
Weight cutting should prioritize performance, not just the scale number.
Lockhart keeps Conor’s camp weight close to his fight-night weight and focuses on consistent fueling, individualized macros, and energy-specific refueling so every training session is productive, not depleted.
Oral rehydration, done scientifically, can outperform IVs over 30+ hours.
Given modern weigh‑in timelines, Lockhart argues that correctly balanced oral fluids (sodium, potassium, magnesium, carbs, caffeine) restore hydration and electrolytes more safely and effectively than high‑sodium IV bags.
Training intensity and tapering must be managed to avoid overtraining and flat performances.
They note fighters often give their best rounds in the gym due to anxiety close to fight night; structured sparring cycles and a proper two‑week taper are crucial, even if fighters emotionally want to “cram” more hard work.
High-level nutrition must adapt to session type, not be static.
Lockhart customizes intra‑ and post‑workout carbs, salts, and calories based on intensity (measured via METs) and whether the work is aerobic or anaerobic, rather than using the same shake or meal for every session.
Promotion and trash talk drive business but complicate respect and regulation.
They acknowledge Conor’s verbal aggression sells massive fights but also contributed to a darker build‑up with Khabib and gave regulators ammunition when justifying discipline after the post‑fight brawl.
Conor’s options remain wide: rematch, Diaz trilogy, or even boxing again.
Despite the loss, Kavanagh believes a Khabib rematch is likely and winnable with adjustments; they also discuss high‑profile alternatives like Nate Diaz 3 or another boxing bout (even Malignaggi or Mayweather) as realistic possibilities.
