With a number of leading riders having been forced out of the previous two grand tours of the year through injury, the Vuelta will begin on Saturday with the likes of Chris Froome (Team Sky), Alberto Contador (Tinkoff-Saxo) and Nairo Quintana (Movistar) at the starting line.
Froome and Contador both crashed out of the Tour de France and have returned in time for a tilt at the Spanish grand tour in an effort to claim a major title in 2014, while Quintana will be back in action almost three months after winning the Giro.
Other big names that will be in Spain hoping to challenge for general classification (GC) honours include the best young rider from this year's Tour - Thibaut Pinot (FDJ.fr), 2012 Giro champion Ryder Hesjedal (Garmin-Sharp) and Joaquim Rodriguez (Katusha), who has twice finished third at the Vuelta.
Rodriguez pulled out of the Giro after a crash on stage six and having battled through the Tour, the Spaniard will see the Vuelta as his best chance this year to win his maiden grand tour title.
The main men that will be missing are 2014 Tour champion Vincenzo Nibali, who has been rested by Astana, and defending champion Chris Horner (Lampre-Merida), who pulled out on Friday due to concerns about his health.
But even without that pair, the Vuelta arguably has the deepest field of GC contenders of any grand tour this year.
"I think so," Evans told the Sydney Morning Herald on the eve of the Vuelta when that point was put to him.
"From a matter of circumstances... through guys being forced out of the Giro...forced out of the Tour through accidents.
"It's the best field in the Vuelta we've had... certainly since I have been racing it."
Evans, the 2011 Tour de France champion, has raced at the Vuelta three times before, finishing third in 2009 when racing for Silence-Lotto.
But this year he will not be BMC's leading rider with the Australian instead set to work for Samuel Sanchez, who finished eighth at the 2013 Vuelta.
It increases the sense BMC do not consider Evans to be their strongest GC contender anymore with the veteran having been overlooked for the Tour.
Evans led BMC at the Giro, finishing eighth, but claimed he is comfortable working for Sanchez over the next three weeks.
"I believe he will be good and our best chance of doing a good GC," the 37-year-old said.
"I'd rather sacrifice my own chances than compromise his. If an opportunity comes to me for a stage, so be it. If not, that's OK."
