I can only assume Rosenthal is referring to my post.

Diamondbacks plan to be sellers at deadline, but extent is still not known: Sources

The Arizona Diamondbacks are telling rival clubs they plan to trade at least some of their veterans. However, the extent to which the Diamondbacks will sell is not yet clear, according to league sources briefed on their plans.
The number of deals Arizona completes before next Thursday’s trade deadline will hinge on a variety of factors, including the level of interest in their players, whether the proposals they receive for their qualifying-offer candidates exceed the potential draft-pick compensation and the assessment of club officials about the team’s ability to compete for the third wild-card spot.
After getting swept at home by the injury-depleted Houston Astros, the Diamondbacks (50-53) sit 5 1/2 games behind the San Diego Padres (55-47), the team currently in the third position.
