I think there is a difference in crossing your fingers and hoping that a magical 10 year competitive window will present itself and being able to see a path for a 5-6 year competitive window and planning around that. Our competitive window should last as long as Acuna is here and that is how we should approach our teambuilding. And talking about all the holes that pop up every season... The Braves really aren't gonna have that many holes popping up over the next few years. Let's assume that we trade for Peralta (2 years) and sign Grandal (3 years). The next person in our starting lineup who would be eligible for free agency would be Peralta in two years. Then we'd lose Freddie and Grandal in 3 years. Ender and Dansby in 4. The rest of our lineup is controlled for 5 or more years. That is a remarkable lack of turnover in 5 years for a starting lineup and its one of the reasons why we should try to create a sustained competitive window while Acuna is here. Another reason is our pitching. We have Gausman for two more years, Folty for 3 more years, and then a TON of pitchers who are still pre-Arb, some of whom are likely to be pretty darn good moving forward. None of this mentions the fact that we still have one of the top 3 farm systems in the game.
We've constructed a team that should have sustained success for at least 5-6 years. I don't believe we should mortgage that to have a 1 or 2 year run at a WS. Once you make the playoffs, I don't believe any team ever has better than a 25% chance of winning the world series. Baseball is a parity driven game. The name of the game should be to make the playoffs as often as possible, occasionally making the move you need that gets you to that 25% mark. That move should usually come at the trade deadline and I'd never make a move that would obviously sacrifice our competitive window for one year. So if I had the choice between a 2 year window where we have a 25% chance at a WS when we make the playoffs each year or a 6 year competitive window where we have a 15% chance, give me the 6 year window all day.
