He no longer has it to mix with fast men,the guy also chokes a fair bit in sprints, he will find away to lose. Did he lose to Gerrans last year in flat sprint? Or coulda been Impey. At least do something on a stage get in break, i hate a guy usualy who does not win a single stage yet get's green, but Sagan i don't mind as much.
I would love Sagan to win cobbled classics, so people don't take it im being harsh on him afterall he is still young i just have huge expectations for him, I personally would go into flanders/Roubaix with tons of race days, who cares about Green now, why waste 21 days to get green every year, have some new goals, if Giro is favourable count that in with you're classic peak and do that then prepare or Vuelta. I agree with poster above i don't thing doing Cali after racing all spring helps him, he even does Suisse aswell, he should do one or other as prep or route de Sud, he cana always comeback later on for Zabel's record.
