If Jacoby's health remains good for the season he will have more stolen bases. He will get more chances because he will be on base more often than Carl.
To be honest, I could careless who steals more as long as they do good. *Like my dad said they will become the first duo to steal at least 50 bases each for the same team since Delino DeShields and Marquis Grissom in 1991.*
By the way, I disagree on Ellsbury beating Crawford by a large margin.
