Just don't personally see any reason they'd trade any of this depth. Some of the young hitters you might target are "sexy" and exciting, but the old "Braves' Way" was the template for this entire exercise - the pitching depth has now been rebuilt to the point that you'd still be a contender if you walked out on that limb an offered big money to an "Ace" like they did when they went after Maddux. If that "Ace" went on the shelf, you'd still have plenty of SPs capable of stepping up to keep you in games.
All the depth Hart & Company have acquired - plus all the picks in a couple weeks - have given you the cushion to actually "miss" on a high-priced free-agent and still stay in the race. There's a HUGE reason the Mutts haven't been willing to give up a deGrom, Syndergaard, or Matz for someone like Tulo - they're one pitch away from losing Harvey forever, will be one pitch away from losing Wheeler forever when he comes back, etc..
It's the "old guy" in me, but I'd NEVER give up 6 years of Syndergaard or Matz AND $118 million for 6 years of Tulo no matter how close I was to winning it all. If the Rockies were willing to eat half of that cash, we might have something to talk about.
TJ or no TJ, the Giants will always regret giving up Wheeler for Beltran just like many people around here love to point out that they'd never have traded Wainright for J. D. Drew.
No matter what people say about lack of hitting baseball will ALWAYS be about pitching and who has the most of it.
