There's been plenty of talk over the last couple years about how much it might cost to maybe extend William Contreras, if he's even interested in doing so before free agency, and/or if Mark A & the rest of the ownership group would even sign off on such an expenditure.
I figured with Cal "Big Dumper" Raleigh signing a six year, $105M extension on the same free agency timeline as Contreras it's as good a time as any to put a bunch of information in one place and try to figure out what that number might be for William (& if it's even a good idea).
Let's start with a comparison over the last two years...
Contreras
1,290 PA | 128 wRC+ | 11.2 WAR
115 AVG+ | 129 BB+ | 91 K+ | 110 ISO+
+11 DRS | +17.7 FRM | 19.9 CS%
Raleigh
1,197 PA | 115 wRC+ | 9.7 WAR
93 AVG+ | 126 BB+ | 122 K+ | 138 ISO+
+19 DRS | +21.2 FRM | 27.1 CS%
Contreras comes out ahead mostly on account of being a better all around hitter versus Raleigh being more of an all or nothing 3TO guy. Raleigh has been a more consistent defender, especially with regards to controlling the run game. The other big factor is that Contreras is a year younger than Raleigh.
FanGraphs had a nice article today on the Raleigh extension and the larger landscape of historical catcher compensation. In it they note that Cal is only the 5th catcher to ever sign a $100M+ deal, so I thought I'd see how past top end catcher contracts turned out, or are turning out for the active guys.
Joe Mauer (8/184)
Before (Age 21-27)
3,578 PA | 135 wRC+ | 34.3 WAR
After (Age 28-35)
4,382 PA | 113 wRC+ | 19.2 WAR
[Mauer got the concussion in the first year of his extension, had two more prime level seasons as a part time catcher in 2012-13, then settled in as a fine (but massively overpaid) first baseman for the last five years of the deal.]
Buster Posey (9/167)
Before (Age 23-25)
1,238 PA | 146 wRC+ | 15.4 WAR
After (Age 26-34)
4,352 PA | 125 wRC+ | 42.7 WAR
[Delivered big for the first five years of the deal, dipped down to above average level in 2018-19, came back for one last big year after skipping 2020.]
Will Smith (10/140)
Before (Age 24-28)
1,966 PA | 128 wRC+ | 15.7 WAR
So Far (Age 29)
544 PA | 111 wRC+ | 2.7 WAR
[Smith's wRC+ has been arrow down pretty much from the jump with a combined 143 wRC+ over his small samples in 2019-20 then a 130 in 2021, 127 in 2022, 118 in 2023, 111 last year. It's the Dodgers so $14M a year for the next nine years is couch cushion change, but this isn't looking like a deal many of the other 29 teams would jump to take on even though he remains one of the Top 10 backstops in the game.]
JT Realmuto (5/115.5)
Before (Age 24-29)
2,910 PA | 110 wRC+ | 19.4 WAR
So Far (Age 30-33)
2,052 PA | 112 wRC+ | 15.4 WAR
[JTR had two prime level seasons to start his record AAV deal, and has followed it up with two closer to average ones heading into his walk year.]
*Yasmani Grandal (5/91.25)*
Before (Age 25-29)
2,326 PAs | 115 wRC+ | 23.4 WAR
After (Age 30-34)
1,982 PA | 109 wRC+ | 10.4 WAR
[This one's kinda cheating since the 5/91.25 is combining two separate contracts and was actually closer to $80M after accounting for the pro-rated 2020, but Yasmani essentially kept rolling for the first three years of big money before falling off the cliff for ages 33-34. He had a nice bounce back last year in a part time role with PIT but remains unsigned.]
So, taking all that into account, it looks like counting on even the very best catchers to be productive much past their 30th birthday is a dicey proposition.
As far as how much Contreras would want to sign on the dotted line? I think he wants the total money and AAV records which at this point would essentially be 8/200. An MVP calibre season (followed by some postseason heroics, but lets not get too far ahead of ourselves) would go a long way in adding to that pursuit.
