Trout has a bWAR around 86. He's more than a mere lock. Other locks are Verlander, Kershaw, Scherzer, and Betts. I'd probably put Arenado and Machado in the very, very likely HoF category.
Paul Goldschmidt is one I'd be concerned about if he doesn't come back to being at least decent. Coming into this season he was on a HoF trajectory, but ooff... hasn't been good this year. He's two years older than Freeman, but has one fewer season of experience. Freeman could pass him next year, in which case I'd think Freeman would probably get in (maybe not on first ballot) while Goldschmidt waits awhile.
Lindor and Correa will be interesting cases. Both in mid-40s in bWAR and should have another 5-6 years of above-average production. I think it'll be a close call for both. Jose Altuve is another borderline guy, but as a 2b, might have a shot if he can have 2-3 more decent years.
In hockey, Erik Staal's HoF case will be interesting. I don't think he's playing this year, but he hasn't retired. If he's done, he's pretty borderline. Just over 1000 pts. 1 AS, 1 Cup.
