Pretty much.
However, his numbers and "information" line up pretty well with what most of us have assumed for a while. Rosenthal's sources have the available money about the same. If the final number is ~ $140 million, AA will have done as it's reasonable to assume he was asked by cutting back from last season's projected payroll - probably not as much as some parts of the ownership group would have liked, but still a significant amount.
It's easy for everyone to lose sight of the fact that spending is down significantly league-wide because they've been talking about the Dodgers and Padres spending stupid cash this winter, but the list of teams with reduced payrolls for 2021 includes...
Arizona, Atlanta, Chicago (Cubs), Cincinnati, Miami, Milwaukee, Pittsburgh, San Francisco, St. Louis (even with the Arenado addition), Chicago (White Sox), Cleveland, Detroit, Houston, New York (Yankees), Seattle, and Texas ALL have lower payrolls - some of them
significantly lower. That's over half the league. Tampa Bay is spending exactly the same amount, Kansas City's payroll went up $1 million, the Angels are spending $2 million more. Baltimore's payroll went up $10 million, but that's because they're paying the Angels that $10 million for Cobb to pitch for them. Take Chris Davis off their roster and their total payroll is less than $40 million. With all their additions, the Mutts' payroll is $3 million more than it was for 2020, and the Phillies' payroll has only gone up $7 million even though they gave Realmuto a record-breaking deal.
The point is, anyone expecting AA to be able to run out and trade for someone making significant money or to sign someone to a substantial deal this late in the game - even if they represent a really good value (without offsetting some of that payroll added by including Ender in the deal or getting someone else to take his money) - is probably going to be disappointed.
