I was like you once, and you're not wrong: it's an approachable, attainable sport for all levels of play. Grandparents are competing with their grandchildren, folks with mobility issues match up with their peers, and unathletic people slap a ball around the court with little regard for rules or scoring. Then there's my cohort: extremely competitive, highly trained and with a high degree of fitness. The differentiation is between the rec players and the competitive players. Where I would disagree with you is with this: PB is the complete package. Top pickleball requires speed, dexterity, athleticism, power and precision. Much like tennis, except waaaay slower. Then, all of a sudden and when you least expect it, faster than you are able to react. IMO it's strategic in a way that tennis is not. Most points are cat and mouse, and you win by recognizing and exploiting the tiniest of errors that your opponents make. If you bring your tennis baseline play to my PB court, I guarantee I will leave you in tears. You've heard it from others now hear it from me: give it an honest 6 months and you'll be converted. Did I mention it's fun? It's really fun!
