To me, Sanchez's ceiling is near-elite defense with a .280 average from the 7 or 8 spot, while his floor is solid defense with a .240 average in the 9 hole.
Meanwhile, Johnson's ceiling is good defense with a .310 average with 50+ stolen bases, and his floor is below average defense with a .250 average and 20+ stolen bases.
Higher risk but bigger reward with Micah.
