With not just free agents, but some of our own home grown stars this is becoming a big question for the Jays - do you lock in a player for a decade or do you say 'screw it'?
Let's dig into some data - I downloaded all the raw data I could from FanGraphs (surprised how easy they made it). So all WAR figures are fWAR. Baseball Reference didn't have a simple method to do this without paying (and even then I don't think they have it without doing lots of stuff that would give me headaches). This is all for hitters only first.
Going by age, there are a handful of players who played pre-18 (109 player seasons, youngest was 14) but none had 502 PA, nor did any get 2 WAR (expectation of a full time player) so we'll ignore those children. 2,677 player seasons had no age, just 13 were full-time, 76 had 2+ WAR, peak of 6.97 for George Shafer in 1884 - the most recent player was from 1948 with the majority (including all 1948 players) being Negro Leaguers (thus never 500+ PA), with all 500+ PA players being pre 1890 (IE: when MLB was more like fast pitch softball). Thus eliminating that data shouldn't affect anything. The oldest full-timer was 43 (Cap Anson) with Carlton Fisk 1 PA shy in his age 43 season (how the heck did a catcher do that?). The oldest to get 2+ WAR was 45 (John Henry Lloyd in the Negro Leagues in 59 games - 365/416/525, WOW, sadly no stats pre age 37 for him as stats are only there for 1921-1929 when he started in 1905). From age 46 on only 11 player seasons exist, with none getting 2+ WAR, so we'll just ignore the post-age 43 data for this exercise (fun, but not really useful).
So of all players playing - what percent are worth 2+ WAR (ie: enough to be worth playing everyday)? It goes from 0% at age 18 to 17.2% at age 31, then dropping to 2.2% by age 43. Limit it to 5+ WAR guys (stars) and compare to full time (as few can do that in under 502 PA) and you go from 0% at 18/19, peaks at 26.4% at 20 (if you get a ML job at 20 you obviously are damn good and forced the issue), and hovers in the 10-20% range until age 36 and hits 0 at 43. At 42 Luke Appling cracked 5 WAR and Carlton Fisk nearly did (4.96) while PED Bonds was at 3.2 for 3rd place. So it is possible, but highly unlikely to be a star at 42. Note: If I compare 5+ WAR seasons to all players it drops to a peak of 3.2% (age 29 - no shock as that generally is seen as the core of a players peak years, with 3.1% at 28 and 30, sub 1% at 39 and beyond).
How many 5+ WAR seasons have occurred? 2331 for hitters all time (2 by Ohtani with just his bat). To be worth $70 mil via bat only that is what he needs to produce - well, actually he'd need to be up to 7 WAR but that ain't happening as a DH. 601 seasons of 7+ hitter WAR seasons have happened, but most had a lot of defensive value. For pure offense you'd need 70+ runs created - only 84 of those have happened ever, fewer than 1 per year of ML history with many being by Bonds, Gehrig (7 each) and Ruth (10). 6 times each for Ted Williams and Rogers Hornsby, 4 for Cobb. Basically only Bonds* has more than 3 of these since integration in '47 (3 of Williams were pre, 3 post inc '47). So yeah, his odds of being worth his deal by just his bat is very, very low.
So, for star level players (5 WAR at least once before age 30 - 766 players) how long do they last after each age and what do they produce? Obviously with each year we get more players added in. FYI: only 26 players have 10+ 5+ WAR seasons with Hank Aaron and Ty Cobb leading the way at 18 each. Bonds the most for guys who played at least 1 game in the 2000's at 17, Rickey Henderson at 12, Ken Griffey Jr.-Miguel Cabrera-Alex Rodriguez-Albert Pujols at 10 each covers all 10+ 5+ WAR season guys who played at least 1 game in the 2000's. All the rest who reached 5+ WAR 10 times played the final game of their career in the 1900-1999 era. This table is all guys with 5 WAR seasons by age, who started in 2013 or earlier (so we have 10+ years of data for them). Bust post 30 is under 10 WAR at 30+, Wow 30+ is 20+ WAR from 30 on up.
