I mean, Jumbo pushed the limits of the law to get Van Aert.
Looking back, that was a turning point for Quickstep. For commercial purposes they really needed that Belgian superstar to replace Boonen. With Van Aert being unobtainable, they've had to double down on the only other potential option, the one they did have... Evenepoel. And while Van Aert would have fit into their setup perfectly, they've had to sign a lot of climbers to be able to support Evenepoel in that department.
Had they been able to get Van Aert, they would likely have dominated the past two seasons on the cobbles without having to sign anyone else, and continued that way for years to come. That's ignoring the other victories Van Aert has had and has to come. By doubling down on Evenepoel, they've forced themselves to neglect their cobbles squad and it arguably cost them Almeida as well. With his contract now running until 2026 and lots of support signings in place as well, they are completely locked in.
And Evenepoel will have to do a lot to make that degree of investment worthwhile. Winning WT stage races, TT worlds and GT stages, which will likely start happening soon, puts Quickstep nowhere near breaking even. Winning Liege and Lombardia once or twice, which he hasn't even been close to but could at least conceivably achieve, probably still isn't enough as they have Alaphilippe for that as well and those races aren't as important to the team as the Ronde and Roubaix anyway. Winning those two races isn't what he was signed for and, as discussed previously, difficult for him, so likely isn't an out either.
That means Evenepoel has to be, at bare minimum, competing for GT wins, in addition to taking monuments, for Quickstep to see sufficient return on their investment. It isn't even certain yet whether he can develop the skillset for that, let alone put it to use. And with such an expensive, long-term contract, it's hard for the team to reverse course and shift money from his support to the cobbles team, because the sunk costs are pretty high at this point. It's been such a monumentally reckless gamble that could mean they don't actually have the next Belgian superstar and also aren't winning the biggest races on home soil anymore. It's also something they almost certainly wouldn't have done, or at least not to this extent, had they been able to sign Van Aert.
Nice to see a thought through argument, but i can't say i agree at all. First of all, Evenepoel started winning big time much sooner than they anticipated. He may (yet) only have 3 WT wins, it is still more than they would have foreseen originally. On top of those, he has had a shtload of GC wins, stage wins and semi-classic wins. Just turned 22, already 25 pro wins. He also has 5 EC/WC medals. And he is one of the most talked about riders in the peloton. Perhaps more than Van Aert, Pogacar, Colbrelli, Alaphilippe, Roglic and Van der Poel. If you check the PCS "most popular" ranking, he's a lot more in the top 10 than those other riders. Check comment sections on articles on cycling media. In Belgian media, he is neck/neck with Van Aert in terms of exposure. So he's bringing in tons of sponsor exposure regardless. In fact, when Lefevere was struggling to find sponsors 2 years ago and was talking about having to disband QS, the sponsors that saved the team, came specifically for Evenepoel. I think Pidcock is earning more, he's older and he currently has * drumroll * one 1.pro win.
You insinuate investing and supporting Evenepoel has cost them financially, yet on the other hand you state that he is the reason they lost Almeida, which is kind of a contradiction... since he was getting expensive (because he too started winning and performing much sooner than expected) and was signed to support Evenepoel to begin with. Before Evenepoel they had Mas, Jungels and De Plus, who all left because they got too expensive. Guys like Knox, Devenyns, Serry, Honore were also already at the team before Evenepoel. So where is this expensive armada that they brought in for Evenepoel that is costing them? Van Wilder and Vansevenant don't weigh on the budget nearly as much as you seem to assume. Vansevenant has been working for Alaphilippe more than he has for Evenepoel, Van Wilder has his own ambitions and will prove to be a much more lucrative deal than signing Knox (again, which they did before signing Evenepoel) for instance. So, you're talking about Masnada and Cattaneo, who have yet to really support Evenepoel significantly? Vervaeke, is really the only rider that fits the discription and he's hardly going to be a big earner as well.
What is currently costing the team's classic performance is Agreen getting Covid, Declerq out with heartissues (due to having contracted covid) and Ballerini waiting a few weeks in order to better time his peak. Not Evenepoel. If anything, he has proven to be their goose with the golden eggs.
The team has started attracting more young riders in general. Steimle, Van Tricht, Bagioli (who is more of an Alaphilippe stand-in than an Evenepoel domestique), Vansevenant, Van Wilder, Vernon, Honore (fcking qwerty keyboard)... Evenepoel, (Almeida). And not all of them have turned into big winners yet and might need time, others never will and were brought in with a different plan. And not nearly all of them have been brought in to support Evenepoel. They have always signed guys like Mas, De Plus, Knox, Honore, Serry, Honore, Jungels... In a team of 30 riders, there are maybe 2 or 3 that they would not have signed had it not been specifically for Evenepoel.
As far as big earners go, Evenepoel has a nice contract but from what i understand not nearly in the league of Van Aert or Van der Poel. I also haven't seen him in those lists of big earners. Or did you think they could have signed/kept Van Aert on peanuts? The reason Jumbo can sign (out of necessity) Benoot, Laporte... is because they have a bigger budget. And Van Aert needs them to get the big wins as well, because often Quickstep has upended him/TJV. So far he has only won one monument, in case you forgot. I think Van Aert + the guys currently supporting him at TJV cost a multitude of what Evenepoel and the guys they signed to support him, cost. Riders you think might be have come for Evenepoel, have already started to work more for Alaphilippe than Evenepoel (Vansevenant, Van Wilder, Schmidt....).
They would have had to invest time as well as money in Van Aert as well. They would have needed to wait for him to become a worldbeater, just as TJV has been doing, just as well. In your premise, you seem to assume Van Aert would have come cheap, Van Aert would have started winning big races from the start and the lawsuit (which is still hanging over TJV's head, because no way Van Aert was going to sign that contract without guarantees that TJV would pay the check) would be settled for peanuts.
So while Van Aert might have turned out to be a great fit for QS in hindsight, you are overestimating the team's current problems. You are overestimating the concessions the team has had to make in order to get/keep Evenepoel. You are underestimating the concessions they would have needed to make to get/keep Van Aert. And you are underestimating what Evenepoel has already brought to the table in terms of wins and exposure and what he will do in the future.
