I don't know if Remco was that much out of form at the Giro. His TT was fine, but he really seems to excell in short hilly races. It's strange, he is very light, should be good at the mountains, but I still need to see if he can do these kind of races. Winning San Juan, Algarve or Burgos is not a key to GT greatness. Maybe he is simply cut for different kind of races other than GT's, and that's the beauty of cycling, I don't think Paolo Bettini or Fabian Cancellara are inferior riders to Cadel Evans or Andy Schleck.
I voted Mas, I fancy him winning a Vuelta if Roglic stays out. Being Spaniard he has better incentives to peak for his home GT than most of other riders. Any other GTI think is highly unlikely.
I voted Almeida, he was the finest rider at this year's Giro third week and really blossomed when Remco went out, he dropped (a fading, yes) Bernal twice in the final stages and has a very fine TT (not as good as Roglic's or Pogacar's though), even if he ended behind Vlasov and Martinez, he impressed me more than both.
Mäder may impress us in the future. Lopez is a one-trick pony and has loads of other issues. Haig and O'Connor I think reached their limit.
