I think Atkins has been fine as a GM (not perfect so Jaysblue don't get your panties in a knot), Schneider has accumulated one of the team's highest ever winning percentages so it's not like he's the worst manager ever (although he's made his share of baffling decisions), Mattingly is about to take over as hitting strategist so I'll wait until he actually performs the job before passing judgement (shocking I know to not jump to conclusions), Guillermo oversaw one of MLB's best offenses in 2 of the last 3 seasons so he's been fine, and the high performance department department has done a fantastic job largely keeping the team's players healthy and on the field (it's not their fault the team has a bunch of bad bodied players who don't seem to want to utilize the resources available to them).
