Because it isn't the most interesting stage, I'd like to draw some attention to the performances of the wildcard teams so far. I think it's a strong contender for the weakest collective performance in the history of the current system, with Euskaltel mounting a challenge for the single worst team to contest a modern GT. None of these teams have made the top 6 of any stage so far!
Stage top-10s:
Burgos - 3
Euskaltel - 0 (!)
Kern Pharma - 2
Best stage result:
Burgos - 7th (Langellotti on stage 5, Ezquerra on stage 13)
Euskaltel - 11th (Canal on stage 2)
Kern Pharma - 10th (Adria on stage 5, Berrade on stage 13)
Best-placed rider on GC:
Burgos - 22nd (Cabedo)
Euskaltel - 35th (Bizkarra)
Kern Pharma - 24th (Parra)
Highest position in a minor classification:
Burgos - 19th (Okamika, points)
Euskaltel - 22nd (Bou, KOM)
Kern Pharma - 6th (Parra) if we count youth classification, but 57th (Garcia Pierna, points) if we don't with not a single KOM point scored all race
And for the statistics that reflect slightly less poorly on these teams:
Team classification (out of 23)
Burgos - 12th
Euskaltel - 14th
Kern Pharma - 15th
Days in the lead of any classification:
Burgos - 3 (Langellotti, KOM)
Euskaltel - 1 (Bou, KOM)
Kern Pharma: 0
Days in the breakaway (out of 14 - must be ahead of the peloton for at least one third of the stage to qualify):
Burgos - 9 (2, 3, 4, 5, 9, 11, 12, 13, 16)
Euskaltel - 9 (3, 4, 5, 6, 11, 12, 13, 15, 16)
Kern Pharma - 5 (2, 3, 5, 11, 14)
Days there wouldn't have been a break without the wildcard teams participating: 2
Combativity awards won (out of 14):
Burgos - 3 (Bol, stages 2 and 11; Diaz, stage 9)
Euskaltel - 2 (Bou, stage 13; Mate, stage 16)
Kern Pharma - 1 (Miquel, stage 3)
IMO, this is a great sign that it's time for additional requirements to the wildcard system. Teams that are lower than the sum of WT and PCT teams (34), should not be eligible. Currently Kern Pharma is 41st, Burgos is 61st and Euskaltel is 63rd. For context, the the highest-placed continental team is in 25th, and 12 of the 13 other PCTs are ahead of them. The 13th is Novo Nordisk, so literally every eligible team that doesn't consist solely of diabetics would add more to the race (in theory).
Also, Caja Rural are in 31st, which shows that even for teams from home nations, being at the mercy of the organiser isn't necessarily preferable to some sort of merit system.
