The list is in no particular order, so I'm not saying that Tim Duncan is better than LeBron James or Miguel Cabrera is better than Mike Trout.
Tim Duncan-Derek Jeter
Both are all time greats. Both are first ballot hall-of-famers. Both also have five championship rings. Tim Duncan, age 38, has played for the San Antonio Spurs his whole career. Derek Jeter, age 40, has played for the New York Yankees his career. This similarities between these two are incredibly close, and actually really strange.
LeBron James-Miguel Cabrera
First things first, both entered the highest professional level in 2003. Cabrera succeeded more in his first year, winning a World Series with the then Florida Marlins. LeBron won Rookie of the Year, something Cabrera didn't accomplish. James has been an All-Star ten times, compared to Cabrera's nine. LeBron has received the MVP Crown four times, but Cabrera has only been an MVP twice. Last but not least, James wears No. 23, and Cabrera wears No. 24.
Kevin Durant-Mike Trout
Here comes the young guns. Durant and Trout have both succeeded in their sports since they were rookies. Durant has more experience than Trout, as Durant has played in the NBA for seven years, and Trout is in the middle of his third. Trout has almost caught Durant on All-Star appearances already, as he has three compared to Durant's five. Durant also just won his first MVP, and Trout may be on his way to his first this year.
Chris Paul-Clayton Kershaw
Our only point guard/pitcher combination makes its appearance here. Paul and Kershaw both may be the best in their sports at the defensive side of the game. Paul has made six NBA-All Defense teams and led the league in steals six times. Kershaw has only been in the league six years, but he is the best pitcher in all of baseball. Kershaw is a 4-time All-Star, a 2-time Cy Young Award winner, and he has a Gold Glove to his credit as well. Both do the things to help their teams win on the defensive aspect.
Stephen Curry-Giancarlo Stanton
In our last comparison, the bombers come into play. Stephen Curry and Giancarlo Stanton are both annually at the top of their respective sports in three-point shooting and home runs. Curry has one All-Star apperance while Stanton has two.
