Obviously, I have been one of the leaders of the trade everyone if it makes sense - (thanks for being my lifeguard Nucksie) and build through smart trades and smart moves.
But, I do admit that it is possible to buy your way to being competitive either through FA acquisition if you have enough money or trade if you have enough money and/or are willing to give up young talent.
What a don't believe in is a half assed rebuild where you dip your toe into the water then decide it is too cold and painful as far as dismantling the team as part of a future build. I also don't believe in some half assed throw the ball up for grabs in the end zone tactic and hope your guy comes down with it where you declare your rebuild over because you need it to be then spend year after year trying to hold everything together with various colors and types of bailing wire and tape (guys like Colon, Dickey, Johnson, etc.). That way leads to failure or perpetual baseball purgatory - not good enough to win anything, not bad enough to fire everybody and rebuild again the right way.
There are those who want the magic pill. They don't want the pain associated with building the hard, right way where you don't have unlimited funds, but also don't want to watch mediocre baseball. They want sugar and spice with no real idea of how that is supposed to happen. In other words, they want to make an effort that falls between minimal and adequate to rebuild then trust luck to arrive.
I'm not that way. I say either grit your teeth and take the 5 year rebuild and do it right, no excuses, no regrets, accept the bad baseball along the way to better days ahead OR proactively work to make your team better in a major way, not some little incremental step process where you know that the sum is still far from the goal but good luck could make the difference once in a blue moon.
