Im starting to think he might actually best suited as a GC rider, in case he can lose a few more kilos.
He doesnt seem to be as punchy as the best in the hilly classics, he doesnt seem to have the best 3min effort, he has an ok sprint at best. Really steep climbs dont seem to suit him either. What he has is a good TT and he seems to do well already on rolling long climbs. Other than that right now he seems to be a rider who is good at everything but doesnt really have on outstanding quality. That way his classics results will never be much better than what they were this year.
