on the one hand, Tatis is a SS so that should be more valuable. On the other hand, it really does look like, with Trout & Betts, with 4 of the 5 biggest contracts being outfielders, I'm not sure that position really factors much into the calculation.
But Trout plays CF and Betts is a superlative RF. Both of them and Tatis have significant value from that. With Soto, the question is how long he can play in the field at all, let alone where.
