Washington Nationals General Manager Mike Rizzo deserves most of the blame for this disastrous start. Rizzo is generally a great talent evaluator and generally puts this team in position to win from the first day of the season.
Rizzo did not do that this season. Although he went out and signed Patrick Corbin to a 6-year $140 million contract, which has proven to be a wise investment thus far, he neglected to address multiple other areas.
On top of neglecting to address other areas, he spent recklessly on three particular players who cost him nearly $25 million.
