Well, I'm happy Phinney won something finally.
I'll say what I said at the beginning of the year. Right now Phinney is a great prologue rider, a very good time trialist at longer distances, and an okay sprint/cobbled rider.
At everything else... he's finishing with the bus.
Even in the best case/fanboy analysis of Phinney, I can't see him ever contending for a race like RVV, let alone anything hillier. He can advance to be a strong helper in a race like that, but I see almost nothing in his past performance to suggest he'll ever be able to survive hills like that, even if he becomes excellent at the Pave.
He needs to keep his ITT and work on the sprinting I think. Perhaps he can advance his climbing to the point he can survive some hills and limit losses in stage races like this... but he's not even close to that yet.
Though I dont' know how compatible becoming a pure sprinter is with maintaining ability on longer ITT's.
