I remain more interested in a team's 25-and-under talent, than the arbitrary distinction involving rookie status. The Cubs major league stats page had a lot more players than the Twins at age 24 or below last year (so 25 coming up); the WAR total bb-ref shows for those players is higher for the Twins, but their total was almost entirely attributed to Danny Santana, who "some" here feel is due for a regression to the mean. Also many Cubs youngsters racked up negative WAR last year (learning curve or just lack of talent, I can't say), and I don't know if it's wiser to subtract or just treat them as zero, in which case the Cubs' WAR total would have been about the same as the Twins. All 5 of the Twins' young'un batters registered positive WAR, including Polanco who gets 0.3 WAR for his 8 plate appearances. Prorated to a full season that would be, what, 20-25 WAR? W00t! I'm glad I take SSS at face value.
