There are a few other names. But indeed, Padun did a Padun, Mohoric was great in his junior/23 days, but ever after that showed nothing close to what he does this season, where he's among the top 5 allrounders, Caruso with the best GT of his career at 33, Tratnik with amazing climbing, Mäder improved to the point of being one of the best coming GT prospects - Haig's performance looks most normal compared, but considering he crashed hard during the Tour it's also quite impressive. Colbrelli - what can you say, the guy has always been good, but wow, how strong is he this year.
I would like a good explanation other than upping their illegal game, but that seems to be the most plausible. It could be a change in nutrition or general change in training approaches or something, but with Padun's weird "I lost some kilos within a week and suddenly I was god for a few days" and the Milan Erzen connection, I have a very, very bad feeling about this.
