So if Remco wanted it and Lefevere wanted it, why haven't they cut the ties with their heritage and done it? As for the rest, lack of support was likely demotivating to some extend, beyond that i don't feel the rest contributed to this years abandonment.
Currently UAE is the only team, full support for their leader, Visma is good at it but not a full support team. Then there is RBH, building up, transforming slowly, IMHO mostly due to Rogla, Beyond that i don't see it ATM. All in all teams do struggle, transitioning and maintaining on what can be called an AAA GT GC orientated team status. So even if both Remco wanted it and Lefevere wanted it, the truth is they never have done it. They remained a strongly classics and Co. focused team and at that Remco is good at, here it would be hard to hold anything against them.
