I think Florida is experts in maximizing a particular window. I don’t look at anything Zito did as a gm that got bored or decided to start doing things to do things. Everything seemed heavily centered around getting players in a narrow age bracket that synced up with the premium draft picks for premium spots (1C, first pair RHD). Zito successfully realized the best opportunity to pounce is at the end of rfa years soon before UFA years when players and their prior teams are heaving towards a natural divorce with team control expiring.
The result has been group of players in a tight age range that hit their prime together and has had a lot of success. Notice how Florida unlike say Dallas doesn’t have players all over the age map right now. Obviously some luck (like home runs from Verhaeghe and Forsling) and and some internal advantages along the way. But this shows how well timed aggression is very beneficial if there’s real thought behind it.
I imagine many will take wrong lesson and just “be aggressive, make trades” but if they aren’t synced up with players you drafted many years earlier, it probably won’t be as successful.
