Loved me some Chourio last night, but I actually think that rather than consistent, he's been maddeningly inconsistent. He certainly has the raw tools to be a HoFer, but I think his first three years have been very different than the guys on the list, each of whom had show legitimate greatness by his age over an entire season.
Matthews- age 21, 8.1 WAR, 2nd in MVP voting
Mantle - age 20, 6.3 WAR, 3rd in MVP
Kaline - age 20, 8.3 WAR, 2nd in MVP
Robinson - age 20, 6.6 WAR, 7th
Bench - age 22, 7.4 WAR, MVP
ARod - age 20, 9.4 WAR, 2nd
Trout - age 20, 10.5 WAR, 2nd
Harper - age 22, 9.7 WAR, MVP
Soto - age 22, 7.3 WAR, 2nd
Yes, he's had some injuries, but we'll be happy if Chourio gets to 5 WAR. More to his inconsistency, much of his production was the six HRs in a week in three weeks. The week where he won player of the week in late May, the week with six HRs in early June, the week in early August with 4 HRs, and then last night. Stretches where he's looked like the best player in baseball, followed by maddening stretches. None of this is saying he won't be a HoFer, but just that he's not shown it yet.
