So, Giancarlo Stanton's contract has me wondering: What would Babe Ruth be worth today?

In his piece for ESPN Insider, Dan Szymborski projected Stanton will be worth $316 million from ages 25 to 37, just shy of the $325 million he'll be getting.

Jeff Sullivan conducted a related study on FanGraphs, comparing Stanton to similar hitters through age 24 and then asking: How would a 13-year contract for those players have worked out in today's dollars?

Jeff looked at the value of the deals under the cost of $6 million per WAR and $7 million per WAR. Henry Aaron was the best comparable player and was valued at $776 million from ages 25 to 37 under the $6 million context. Alex Rodriguez, Frank Robinson, Miguel Cabrera, Mickey Mantle and Albert Pujols also topped $500 million of value. Heck, even Will Clark came in at $308 million. Boog Powell topped $200 million. BOOG POWELL! Who never made an All-Star team in his 30s and was basically done at 33.

Hmm.

OK ... if Will Clark was worth $300 million, what about Babe Ruth? I mean, no offense to Will Clark. Ruth wasn't in Jeff's study. What would the Bambino be worth today?

I combined Dan's system with Jeff's system. I assumed each win above replacement was worth $6 million with 5 percent annual growth. I then plugged in Ruth's year-by-year WAR from Baseball-Reference to get a value for each season. Here's what we get at each age:

25: 11.9 WAR ($71.4 million)

26: 12.9 WAR ($81.3 million)

27: 6.3 WAR ($41.7 million)

28: 14.1 WAR ($97.9 million)

29: 11.7 WAR ($85.3 million)

30: 3.5 WAR ($26.8 million)

31: 11.5 WAR ($92.5 million)

32: 12.4 WAR ($104.7 million)

33: 10.1 WAR ($89.5 million)

34: 8.0 WAR ($74.5 million)

35: 10.3 WAR (100.7 million)

36: 10.3 WAR ($105.7 million)

37: 8.3 WAR ($89.4 million)

Holy ... that's $1.06 billion of value. Babe Ruth, the billion-dollar ballplayer.

Let's do two more all-time greats.

Willie Mays comes in at $931 million, topping out at $104.2 million at age 34 when he was worth 11.2 WAR.

Barry Bonds comes in $916 million, topping out at a whopping $127.1 million at age 37. (Our theoretical contract doesn't even cover Bonds' age 38 and 39 seasons, when he was worth 9.2 and 10.6 WAR.)

Of course, I'd suggest this methodology breaks down at the extremes. It's one thing to pay a one-WAR player $6 million on a one-year contract but something different to pay a 5-WAR player $30 million over many seasons. In fact, you can argue that teams have limited their contracts on the upper end. Clayton Kershaw's AAV is $31 million even though he's averaged 7.0 WAR of value the past four seasons, suggesting he should have at least topped at $42 million, or even higher given inflation.

Stanton's AAV comes out to a mere $25 million -- although much of that is backloaded in the final seven years of the deal, so this does look like a short-term play by the Marlins. Maybe Stanton will be worth $25 million a season.

But if he is ... well, just imagine a contract for a reincarnated Babe.
