2-part hierarchy question :

A) For hierarchy considerations is one better or worse or a wash of error/range listings between a D/A+ or A+/D+ ? Despite the appearance of an 'A', are both cases horrible in that either there'll be no errors cuz you didn't get to any ball in play, or you'll get to everything but then fumble it ?

B) What's the hit going from any other position to 1B ? I have a backup 2B A-/B-.

depends a lot on the position. D/A+ at first base is going to be vastly superior to A+/D+. in the outfield it's closer but I'd probably prefer D/A+ (depends on how good the A+ is, there is a wide range within A+). shortstop the A+/D+ is a no-brainer.

you can play anyone competent at another position at first base. that 2B will do very well.
