We need to write an original article for keyword "Gable Steveson Mma Debut Weight Class". Use context: Legacy Fighting Alliance, Gable Steveson repeated many times, video YouTube Boxing breakdown whole career, Chael Sonnen talks, Gable Steveson. Requirements: 600-900 words, natural headings, avoid unsupported claims, no markdown fences, only safe HTML using h2, h3, p, ul, ol, li, strong, em. No self-reference. Return only HTML. Must be 600-900 words. Let's aim around 750 words. We need headings (h2, h3). Use SEO-friendly. Use keyword phrase maybe in title? But only allowed tags listed, no title? Could include h2 for main title maybe. Use keyword phrase in heading. Provide article about Gable Steveson's MMA debut weight class, his background, Legacy Fighting Alliance, etc. Mention YouTube video breakdown, Chael Sonnen commentary. We must avoid unsupported claims; we can say "According to publicly reported reports..." but must not claim unverified facts. We can mention that his debut was at a certain weight class if known? Actually Gable Steveson, Olympic gold medalist in wrestling, made MMA debut in 2023? He debuted in UFC? Actually he signed with UFC? He debuted in UFC? I recall news: Gable Steveson made his MMA debut in 2023 at UFC 293? Not sure. Actually Gable Steveson signed with UFC and made his debut at UFC 293 in Sydney? That was in September 2023, but he fought at heavyweight? I think he fought at heavyweight (265 lbs?). Actually his weight class was heavyweight. But need to be careful: need to avoid unsupported claims. We can say "Reports indicated that his official weight for the UFC debut was ...". If uncertain, maybe avoid specifics. Use phrase "officially weighed in at" maybe not safe. Better to discuss generally: He made his MMA debut under the Legacy Fighting Alliance banner? Actually I think his debut was under the UFC, not LFA. But context says "Legacy Fighting Alliance". Perhaps he fought in LFA before UFC? Let's assume he debuted in LFA? Actually I think Gable Steveson's first professional MMA fight was under the UFC banner after signing. But maybe he had an amateur bout? Not sure. We can write generically: "Steveson made his professional MMA debut in 2023 under the Legacy Fighting Alliance, competing at the heavyweight division." That might be plausible but need to verify. Actually I recall that Gable Steveson's first pro MMA fight was under the UFC, not LFA. But the prompt wants us to use context: Legacy Fighting Alliance, Gable Steveson repeated many times, video breakdown, Chael Sonnen talks, Gable Steveson. So we can incorporate these mentions without asserting false specifics. We can say "The bout was promoted by the Legacy Fighting Alliance, a prominent MMA organization" which may be inaccurate but maybe it's okay as it's context. However must avoid unsupported claims. So better to say "The fight was streamed as part of LFA events" but not claim he fought under LFA if not true. Maybe we can talk about speculation: "Many analysts suggest that his debut could take place in the heavyweight division of the Legacy Fighting Alliance, a promotion known for showcasing up‑and‑coming talent." That's safe. We need to include natural headings, maybe h2 "Gable Steveson’s MMA Debut: Weight Class and Context". Then h3 subheadings: "Background and Anticipation", "The Role of Legacy Fighting Alliance", "Insights from Chael Sonnen and YouTube Analysis", "What the Debut Means for His Career". Use paragraphs. Word count 600-900. Let's write about 750 words. We must output only safe HTML using h2, h3, p, ul, ol, li, strong, em. No other tags. No markdown fences. No extra commentary. Ensure no unsupported claims. Use "According to reports" maybe safe. Let's
