It is fair to say that Konig's upper limit as a GC rider isn't really clear yet. He has participated in 4 GTs and was allowed to ride for GC in 3 of them, all 3 times finishing top 10. That's a pretty good start. However, he wasn't remotely near contesting the win in any of them and at 28 he needs to improve quite a bit to seriously contend in the future.
It's also fair to say though that he is very unlikely to get many opportunities to lead at Sky. Particularly as he has never been the kind of rider to perform at a high level in many races throughout the year, which is how Sky riders move up the pecking order. Without wins or regular very strong domestique performances, he won't be given the roles fought over by riders who show their strength often in other races. Sky don't indulge riders who base their whole season on a GT minor placing.
