I think Leov was a much more experienced rider so he had less to learn, he just wasn't bat**** crazy so he lost time in the tech compared to the younger guys. Brook on the other hand is so some smart thinking could help him win more. On the other hand Blenki trains with Nico and it gave him nothing in terms of results.Apparently Brook will be on Trek next year. Dunno if that's good news. He could improve riding with Gwin but he also could stand in Gwins shadow like Leov.
