If the team did not think Beste would be good enough to open preseason with the first team, he shouldn't even be an option at this point in the season. Thats just searching way too deep on the depth chart. Beste isn't going to be a Dortmund first team player.
And I don't think our U-19's have that many eventual options for the first team, anyway. I like Kilian, I think he might've been with the first team in preseason, if we didn't have a trillion CB's with the first team in preseason, already. Maybe next season or for the second half of the season. Kopacz was the only player promoted for preseason who I thought had first team potential, but he's not really an immediate option. Maybe he tears it up this season with the 19's, and then goes out on loan. I'd say its an outside chance he might be a Dortmund player. Logjam at the positions he plays, also. Kehr looks to be a good player, but how will he be after he returns from that injury? Unbehaun is the star of the academy, besides Moukoko, but Moukoko is way too young to even start discussing towards the first team. I hope that Unbehaun can continue his progress, and be considered for the 3rd GK spot with the first team next season, although he might need two seasons. He can be our answer to Fruchtl in Bavaria.
