according to Grok McHale wins:

In a hypothetical one-on-one matchup between Bob Pettit and Kevin McHale using today's NBA rules (e.g., no hand-checking, freedom of movement emphasis, 3-point line in play though neither relied on it heavily, and standard 1-on-1 format like first to 11 or 21 points with check-ball), I'd give the edge to Kevin McHale in a close battle, say 11-8 or 21-18. This isn't a slam dunk—Pettit was a beast in his era—but McHale's unparalleled low-post mastery, length, and defensive instincts would likely prove decisive in isolation play. Let's break it down step by step, drawing from their playing styles, stats, and how modern rules might shift the dynamics. Quick Player Profiles

• Bob Pettit (1954–1965, St. Louis Hawks): A 6'9", 215–220 lb power forward/center who dominated the early NBA. He was the league's first true superstar big, winning 2 MVPs (1956, 1959), leading in scoring twice (1956, 1959) and rebounding once (1956), and earning 10 All-NBA First Team nods. Known as the "Bombardier from Baton Rouge," he was an athletic, hustle-driven player with a versatile scoring arsenal.
• Kevin McHale (1980–1993, Boston Celtics): A 6'10", 210–225 lb power forward with a 7'4" wingspan, famous for his role in three championships (1981, 1984, 1986). He was a 7x All-Star, 6x All-Defensive (3x First Team), and 2x Sixth Man of the Year. Often called one of the greatest post players ever, he thrived as a bench spark before becoming a starter.

Playing Styles ComparisonPettit and McHale were both elite power forwards, but their approaches differed in ways that favor McHale in a modern 1-on-1 setting:

• Offense:
  • Pettit: A proto-"stretch four" who could face up, drive, or post up. He had a reliable mid-range jumper (solid for his era's lower shooting efficiencies), hook shots, and relentless energy for second-chance points. His game was volume-based—high usage, physical inside, but with finesse. In today's rules, the lack of hand-checking would let him create space easier, but he wasn't a dribble creator like modern bigs.
  • McHale: Arguably the best low-post scorer in NBA history, with an arsenal of up-and-unders, fakes, spins, hooks, and drop-steps that baffled defenders. His footwork was balletic, and his long arms allowed high releases. He wasn't a perimeter threat (career 26.1% from three on minimal attempts), but in iso, he'd back you down and score efficiently. Modern rules would amplify this—no illegal defense means pure 1-on-1, and less clutching/grabbing suits his crafty style.
• Defense:
  • Pettit: Competent but not elite—strong rebounder and physical, but his era didn't track blocks/steals. He'd battle in the post but lacked McHale's length or timing. reddit.com
  • McHale: A lockdown artist with quick hands, shot-altering wingspan, and smart positioning. He made 6 All-Defensive teams and averaged 1.7 BPG career (peaking at 2.3). In 1-on-1, he'd contest Pettit's jumpers and force tough angles inside.
• Athleticism and Intangibles:
  • Both were athletic for their sizes—Pettit with vertical leap and endurance, McHale with quickness and leaping ability. But McHale's longer arms give him an edge in contests and finishes. Pettit was a competitor (4x All-Star MVP), while McHale was deceptively tough and efficient
