Should Piano Design the New New Whitney?

Architecture critic James Russell, in today’s Bloomberg, has the guts to publish what CultureGrrl thought but dared not say: Renzo Piano may not be the Whitney Museum’s best choice as architect, as it relocates its proposed expansion from well-mannered Madison Avenue to the gritty High Line. Russell writes:
The Whitney has pledged to continue with Piano, but his Madison Avenue design expressed constraint rather than aspiration. The museum’s intentions would be more convincing if it chose an architect who could create the robust presence the Gansevoort setting demands. It does not need another of the spindly glass-and-metal pavilions—impeccable in their way—that Piano has reproduced in an increasingly formulaic way since Houston’s brilliant Menil Collection of 1987.
The problem is: How, at this late date, could the Whitney possibly dump Piano, who has patiently devoted so much time to designing, tweaking and defending the most recent of the museum’s three aborted expansions? And how could you pitch this project to other big-name architects, given the Whitney’s dithering track record? Has anyone contacted Diller Scofidio + Renfro, who are already at work reimagining the High Line?
