Think you need three Mt Rushmores personally:
Batting: Grace, Bradman, Richards, Tendulkar Bowling: Marshall, Warne, McGrath, Murali All Rounders: Sobers, Dev, Botham, Khan
If I had to consolidate these to one, would say Bradman, Sobers, Richards, Warne (essentially saying Wisden was right with their cricketers of the century - only Jack Hobbs missing - Hobbs would be my 5th choice on the batting mountain).
Reggie Cleveland All Stars Mt. Rushmore (white guys w/ black guys’ names & vice-versa) Howie Kendrick Troy O’leary Rulon Jones & Reggie Cleveland
Long Distance Runners
Joan Benoit Samuelson Abebe Bikila Paavo Nurmi Emil Zatopek
You’d have to consider Mo Farah as well I reckon seeing as he’s done the Double (5k/10k) Double (Olympics and World) Double (all of it twice)
