Say what you will but Ty Cobb would be my first and probably only consistent addition. The other three would probably change by the day.

Just thinking about the four major sports the first four names that come to mind are: Ty Cobb, Bobby Orr, Julius Erving, and Jim Brown.

Same here. As a Bills fan I wish it could be Jerry Rice for football but Brady earned it by a long shot.

Caitlin Clark
Larry Holmes
Kyle Busch
Fernando Valenzuela

I'd probably stick to the four major sports if a monument is being built, but I just saw a documentary on Eddie Feigner and it's hard not to be impressed by what he could do and what he did for a long as he did it

Babe Ruth
Muhammad Ali
Michael Jordan
Pele

My personal one would be

Babe Ruth
LeBron James
Wayne Gretzky
Tom Brady

With Lionel Messi being close, but I was never much of a soccer guy

Displayed left to right
Ruth
Jordan
Brady
Ali

Ruth would be upfront where Washington is ,
Jordan
Brady would be tucked in the hole where Roosevelt is,
Ali would be where Lincoln is because he deserves his own rock (area)

Have to go with Jay Buhner here.

all baseball homies
 

Dan Brouthers
Ty Cobb
Ernie Harwell
Charles Gehringer

Great thread, I have enjoyed browsing through all the picks. The OP said, "your" Mt. Rushmore - not the statistically most correct Mt. Rushmore.

I probably go with:

Ruth
Ryan
Aaron
Paige
