In fact, the Marlins would have the potential to be that rare team to feature at least four position players with a WAR (wins above replacement) of 5.0 or higher. Here is the career-best single-season WAR for each player, via Baseball-Reference.com:
Now, that's a little misleading, as Pujols' 10.9 season came in 2003 and Ramirez was injured and struggled in 2011. Here are the 2011 totals for each player:
Only 29 teams since 1901 have had four five-win position players (two had five and only the 1939 Yankees had six). The last teams with four such players were the 2003 Braves and Cardinals.
Marcus Giles: 8.2 (yes, Marcus Giles)
Gary Sheffield: 7.6
Javy Lopez: 6.6
Andruw Jones: 5.1
(Even though he posted a .402 OBP, Chipper Jones graded as 3.6-WAR player, with bad defense in left field contributing to that.)
Jim Edmonds: 7.3
Edgar Renteria: 6.5
Scott Rolen: 5.1
The 2001 Mariners -- who won 116 games -- had five five-win players:
Bret Boone: 9.3
Ichiro Suzuki: 7.6
Mike Cameron: 6.4
Edgar Martinez: 5.5
John Olerud: 5.3
(The 1972 Reds, with Johnny Bench, Joe Morgan, Pete Rose, Tony Perez and Bobby Tolan were the other team with five five-win guys in their lineup. The famed 1939 Yankees had six: Joe DiMaggio, Bill Dickey, Charlie Keller, Joe Gordon, Red Rolfe and George Selkirk.)
Anyway, having four players of such high caliber would certainly be a rarity, as its happened just 10 times in the past 30 years.
For 10 years and $220 million, maybe the Marlins will make it happen.
