The discussion started with the assumption the team would not be strong enough to support him going for GC at next year's TDF full on. So i basically started proposing a hypothetical team that could support him for GC over 3 weeks. As we all know, QS doesn't have top level GC doms like Jumbo or Ineos, so it would make sense that you divide the load over the riders that you actually do have. QS doesn't have a Martinez, a Van Aert, Kuss, Benoot or Van Baarle. So in order for the plan to work, you need to have a team that is willing to pick up the slack of others when others have an offday, get injured, crash out or simply can't deliver each day for 21 days because they will need to go in breaks to compensate missing top-end climbing doms etc. In that case you might think twice about bringing a rider who is going to be doing his own thing most of the time. And if you force him to get in line, maybe this rider doesn't really want to be there himself to begin with. Especially if he can't bring his sidekick.
If you have a support team with guys like the ones i mentioned, then indeed you don't need 7 guys working for him. But when you have to make due with Masnadas and Vansevenants, then you need to get the most out of every spot available. That is the reason i proposed a solution that might not include Alaphilippe. But obviously, i didn't realise some people might feel personally offended by the mere notion and start namecalling.
I already said that maybe it's not a bad thing to not take a full GC team to the TDF, considering it will only add pressure and having someone like Alaphilippe doing his own thing could actually relieve the team of some pressure. But in case you do get into the lead early (be it due to a TT or whatever) your team might come up short.
PS: I also think there is a huge difference between Van Aert and Alaphilippe and i believe you very well know that. Not only has Van Aert won more stages in fewer years in the TDF than Alaphilippe, he has also worked very hard for the team/leader in every TDF he did, and was extremely valuable as a domestique.
