That is no way the same as the spring classic. The cycling calendar needs a reboot after the Tour with more focus on better fall classics. SS, Bretagne, Hamburg, Quebec, Montreal and Paris-Tours is nowhere near good enough. And now they even moved and castraded Milano - Torino.
well, indeed, the spring classics are really a period in the year you look forward to as a cycling fan, while in autumn there are still some nice classics, but the period as a whole is not really getting fans thrilled like the spring. Although I think it would be difficult to copy the kind of build up the spring classics have now , first some semi-classics with a lot of history, paris-nice, Tireno to build up tension to the big races. Later in the season people already had there first goals of the year, and more injuries and how much energy is left is deciding for what races the riders are still peaking. However, it would be cool to create a kind of sequence of big races in the weekend and on Wednesdays in September and October, like now in March and April. It would be interestin in my opinion if there would be some (small) block with really (cobbled) classic kind of races. As those riders not really have a second chance in the season after spring is over.
Fantasy mode on: It would be cool if they could create some new races, like for example a kind of mixture of Flanders and Liege in Yorkshire, should be possible to add an excellent hilly cobble classic there. As well as e real flat cobble classic in Eastern Germany/Western Poland. If you add World Championship, Torino + Emilia + Lombardia, San Sebestian, and upgrade the courses of Brussel Cyclassic (South of Brussel there a quite some unknown cobbled hills) and bring back distance to Paris - Tours and Plouay and you could have a really nice sequence of interesting races, with great possibilities to race on.
