Baseball has seen its fair share of icons, cult heroes, and true Hall of Famers. But then there’s another group—guys who thought they were all-time greats even when the stats, the fans, and sometimes their own teammates told a different story.
These are the players who strutted like stars, talked like MVPs, and played like…well, not quite. From big personalities to even bigger egos, here are 15 MLB players who were absolute legends—at least in their own heads.
15. Delmon Young

Delmon Young played with the swagger of a superstar, even when his numbers screamed otherwise. He always carried himself like the best hitter in the league, despite being more of a one-season wonder.
14. Ian Kennedy

Ian Kennedy once had a strong year and seemed to think he was the next Pedro Martinez. The confidence never dipped, even when the ERA skyrocketed.
13. Billy Butler

“Country Breakfast” acted like a middle-of-the-order menace, but his career was more meatloaf than filet mignon. He talked a big game for a guy who had trouble beating the shift.
12. Carl Pavano

Pavano showed up to the Yankees with ace energy and a starter kit mustache. Too bad he spent most of his tenure on the injured list, acting like a misunderstood legend.
11. Yasiel Puig

Puig played with undeniable flair and acted like a generational talent every night. Unfortunately, the consistency never matched the confidence.
10. Jonathan Papelbon

Papelbon closed games like he was the king of baseball, with the attitude to match. But the bravado often outweighed the actual value on the field—especially in his later years.
9. Joba Chamberlain

For a brief moment, Joba looked like the Yankees’ next great thing, and he certainly bought into the hype. The problem was that the “next Rivera” narrative never quite materialized.
8. Rick Ankiel

Ankiel carried himself like a baseball unicorn—pitcher turned outfielder with movie potential. He definitely had a unique journey, but not quite the Hall of Fame one he seemed to believe was coming.
7. Jose Guillen

Guillen walked like a superstar and talked like a clubhouse savior. But his attitude often did more damage than his bat could fix.
6. Luke Scott

Scott brought a ton of confidence, questionable takes, and the vibe of a self-proclaimed franchise cornerstone. In reality, he was more of a flash in the pan with a loud voice.
5. Lenny Dykstra

Dykstra never lacked self-belief—he truly thought he was larger than life, on and off the field. While gritty and occasionally electric, his legendary status mostly lived in his own mind.
4. Brett Lawrie

Lawrie played like every game was Game 7 and acted like every at-bat was Cooperstown-worthy. His intensity was real, but his ceiling was a lot lower than he thought.
3. Nyjer Morgan

Tony Plush, Morgan’s alter ego, had all the theatrics and drama of a baseball superstar. The on-field performance just didn’t live up to the off-field persona.

2. Milton Bradley

Bradley played the game with a chip on his shoulder and the conviction of an all-time great. The talent was real, but the chaos often drowned it out—and he never seemed to notice.

1. Brian Wilson

Wilson had the beard, the bravado, and the belief that he was a baseball icon. While he had some legit closing moments, the legend of Brian Wilson grew far bigger than his résumé deserved.
