If we are a little creative one could say that 10 of those 20 teams are still around.
Rabobank -> Jumbo-Visma
Davitamon Lotto -> Lotto-Dstiny
Illes Baleares -> Movistar
Cofidis
Quick Step
Liquigas -> EF (Liquigas -> Cannondale and Cannondale merged with Garmin)
Lampre -> UAE
Bouygues Telecom -> Total Energies
FDJ
we could add Chazal-Casino-AG2R and Arkea (Bretagne in 2005)
also Liberty Seguros became Astana in 2006
