This may be "the new normal" in baseball, for a team to have a 3-4 year window followed by a 3-4 year period of rebuilding. If so, I can handle that. One of my most entertaining seasons was the last half of 2015, the last half of the downswing. After Lovello took over, watching Mookie, JBJ, et.al. play the game like they were enjoying it was pleasurable for me.
As I said, I can handle the rich years/lean years cycle. IMO it's far better than being continually mired in 3rd place year after year while the GM continues to play musical chairs with the talent, trying not to lose but also not being committed to winning it all. [Hear that, Ben?]
