Sure Ferrari won their first constructors championships in 1999 with Eddie Irvine but Michael Shumacher really did bring the team back to dominance. Shumacher sat out for most of the 1999 while Irvine was out wining races for Ferrari. In 2000 Shumacher brought Marinello back its wining ways becoming Ferrari's first world champion in 20 years. Michael Shumacher might have been the reason why Ferrari is the greatest F1 team of all time.
