April fools!
Each offseason a move is made by a team that at the time seems like a great idea. Most of the time when a free agent is given a large contract it ends up benefitting everyone. That being said, multiple times this has not been the case.
Take the Rockies, for example. When fans look back on specific trades and signings, there is plenty of optimism. Carlos Gonzalez turned into one of the best players in the team’s history, and most people had zero idea who Gonzalez was before his arrival in the Mile High city.
