Dodgers president of baseball operations Andrew Friedman and owner Mark Walter basically admitted that LA's front office has carte blanche with the Guggenheim Group's money. Friedman said at the Winter Meetings, "We're in a really strong position right now, financially," and Walter added, "[The front office] makes all the decisions. I just tell them yes."
The Dodgers could afford to sign Kyle Tucker to the $400 million deal he wants (but probably won't get), if it weren't for their concerns about their aging roster. They signed Edwin Díaz because they could. Anyone else would've had to ride with Tanner Scott through the rest of his four-year deal.
