This appears to be the way we're looking to free up some roster space - perhaps some salary room too.

D-backs trying to trade aaron hill, but in market stocked with better (kendrick, desmond, Rollins, etc) -- very tall task

Yes, at the present time, it's hard to see a team opting to trade for Hill over the available free agents mentioned - perhaps Jimmy Rollins less so, but Howie Kendrick and Ian Desmond are both likely to perform significantly better than Aaron Hill in 2016.
