I'm not entirely convinced that RFC couldn't have attracted the players without EBTs.
Rangers:-
Klos, Ricksen, Moore, Amoruso, Numan, Konterman, Reyna (Caniggia 66), de Boer, Ferguson (Hughes 87), Flo, Mols (McCann 74).
RFC line up fron Old Firm game in 2001 - all either signed from Scottish teams (Caniggia, McCann), ageing old pros (de Boer, Mols) or attracted during the 'boom' period of Scottish Football in 1997 to about 2003.
