They were very competitive in 2013, but no playoffs...especially second half, they really ended the season on a high point and then carried it on into the following year.
Two World Series in a row in 2014-15, then they REALLY spent a lot of money in 2016 and 2017. Too many injuries, Gordon fell off the map, etc. Let's not forget how the Yordano Ventura death set that franchise back, not unlike the Fernandez situation with the Marlins, he was always going to be their future ace and franchise pitcher.
Not unlike our 2005/06 situation. They broke the franchise record for payrolls every year from 2013-2018, afaik.
