I would have no qualms about giving up Stiever and Walker for Nimmo. Stiever came out of nowhere to have value and Walker may not have the pop we would want from a corner outfielder. Also, Nimmo would essentially be replacing Walker anyways. If those two and a lesser prospect could net Nimmo, I would be all for it. Nimmo will just be turning 27 to start next Spring Training, he has the draft pedigree (former 1st rounder), has good career numbers in the majors so far, and is a lefty bat.
