I almost lean this way, but two things don't align with it.
First, we're not even playing the kids. Which means either they forced these kids on Nick when he didn't want them, or they did not expect the kids to be ready. If it is the former, they should have put a different coach in place. I think it's the latter.
Second, they have no solid record of getting strong immediate performance from youth. Taty scored 1, 11 and 6 goals in 2018-20 (2018 a half season). Talles scored 2, 7 and 4 his first 3 years. Thiago Andrade 4, 5 and 1. Medina 6, 3, 5 and 9. Even Jack Harrison was only 4 and 10. Pereira moderately better at 8 and 6 in 1.5 seasons before transfer. Santi 3, 4 and 5 (with 10 assists in Year 2). And Santi was 21, at the high end of the youth range among these guys. I think the club has made mistakes, and can make them repeatedly (see thread title), but I don't think they suddenly expected the 2024 teenagers to outperform all their prior teenagers.
I also circle back to the Cushing interview clip I posted a week or two ago where he is talking about a long horizon development project for this team.
I think the big fail from the club perspective is the Bakrar-Santi combo. Bakrar showed up 16 games ago, nearly half a season. They are 24 and 23, not fully mature mid-career players but not green kids either. They both start every game when available. Combined they have 8 goals and 3 assists in those 16 games. That's not enough for a starting 9 and DP 10/swiss army knife who should be the engine of the team. And after them there is close to nothing. We used to get a non-insignificant number of goals from our CBs, and our 6, and at least one fullback. None of that has been replaced.
I think the other possibility is that CFG thought the kids should be good enough when they signed them and Nick realized they are not ready once they arrived and he saw them in practice against MLS-level defending.
Based on how things have been playing out I often wonder if Nick is talking to the higher-ups at CFG as much as he is talking to the fans when he gives quotes like he did in the interview you posted. He's telling CFG you think you gave me a team but you gave me a development project, it's going to take time.
I was thinking the same thing about the Lee Q&A where he talked about how difficult roster building is in the MLS and how careful you have to be about how you use the different roster mechanisms because getting the wrong player or the right player but at the wrong price can set you back. The specific comment about getting the right player but at the wrong price seemed like it could be a subtle comment toward CFG about how negotiations went down with both Santi and Martins. Both were intra-CFG transfers and both could have been under the DP threshold if we had been able to get them at a slightly different price. When things are getting negotiated between teams under the broader CFG umbrella I wonder if CFG higher ups are just working out a number and Lee is there trying to explain to people that certain things about the number matter far more than any of them are used to in all the other leagues they deal with.
