Not with the Blue Jays, but with the fans.
According to the Times:
I know people still like to debate it. Debate all they want, I think [not trading for Santana] was the smart and right move, and we’re stronger than we would have been with one player and the money attached to the player without all the extra players we have now.
Cashman confirms the pieces for Santana would have been Melky Cabrera, Phil Hughes, and Jeff Marquez.
Two are on the major league roster, and Marquez was traded with Wilson Betemit for Nick Swisher.
Cashman says that the payroll is too high already. Halladay costs about $7M for the rest of the season.
On the other hand, Cash doesn't think the waiver wire will be a problem to use because teams don't have the cash available to risk taking on a player in a block attempt.
