28 years ago today was the Jays trade with San Diego. WAR didn't exist of course but got into a discussion about the trade and tried to find a comparable today.
To Jays
Alomar 20 years old, 3.9 fWAR in his rookie year
Joe Carter 30 years old 1990 -2.0 fWAR, 1989 1.8 fWAR, 1988 3.2 fWAR 2 years left on his contract as a top 10 paid player (crazy that $4M was top 10)
to SD
Fred McGriff 27 years old 1990 5.5 fWAR, 1989 6.4 fWAR, 1988 6.6 fWAR 2 years of Arbitration remaining. Signed a 2 year extension after the deal (4 years $16M the 5th biggest contract)
Tony Fernandez 28 years old 1990 4.9 fWAR, 1989 3.6 fWAR, 1988 4.4 fWAR. 3 years left on his contract at an AAV of $2.2M.
Best example I could give was Houston trading Altuve (him being the equivalent to McGriff after the extension) and Springer for Soto and Zimmerman. Worked out mostly because Olerud and Winfield/Molitor more than replaced McGriff/Olerud.
It's still one of the most interesting deals to look back on, and knowing that a similar deal will almost never happen again. I apologize in advance for the upcoming Olerud post.
