I would say that Escobar will be solid SS for the coming 10 years. His D is just above average....I don't see GG's in his future. I do see .290-.310 avg with some pop. His numbers will spike for 2-3 seasons and perhaps he will see an all star appearence or two. Time will tell.
If they both stay in the NL....I think he will be playing in Tulo's shadow over the next 10 years.
