I guess having a lot of money to spend is the first step, their building blocks seem non-existent (yes they've had some waiver wire success, but you're not building around Yas, Dickerson and Dubon) and they don't have this incredible farm system that's about to dumps lots of talent onto the ML roster.
I guess they can try to buy a winning team through Free Agency, but history suggest that's often unsuccessful.
Seems odd - usually it's teams that have that solid base there, with a stocked farm system who see a window to contend and use free agency to put them over the top. I just don't see the Giants being anywhere near that. I just see a horrible roster that should probably be selling high on Yas, Dickerson and Dubon to try and rebuild. Maybe add some short term FA's that you could sell at the trade deadline to add talent. Maybe it's just me though.
