From what I read, Chicago offered him the biggest contract. Looking at the deals the Giants made, they clearly have enough payroll to match/go over Chicago's offer and still sign Joc Pederson on that one-year deal.
Farhan and Baer are going all-in with their farm system and that's great. But after the first 9 games of the season, Seiya's production better than all the Giants' outfielders. I don't see how Slater and or Duggar are valued more than Suzuki at this point. IMO, I would've kept Duggar for his speed on the bases and let Dubon or Slater walk.
With Heliot Ramos, Matos, Luciano, and even Bishop on the wings. It looks like the Giants will be fine.
But coming off a big year with 107 wins, signing an big name from Japan, along with all the signings they've done this year, would have a been great.
