  Using the QGP motivated threshold model, where all the $J/\psi$'s are
suppressed above a threshold density, we have analyzed the latest version of
the NA50 data on the centrality dependence of the $J/\psi$ over Drell-Yan
ratio. The data are not well explain in the model, unless the threshold density
is largely smeared. Large smeared threshold density effectively excludes
creation of any deconfined medium in the collision.
