I agree that making the rosters that early is quite problematic, but it happens everywhere nowadays
At least one article says that now that Dresden qualified for CL they try to collect more money in order to be able to sign a 13th player.
I guess Ziegenbalg as 4th OH will be ok if the other three (Lorber Fijok, Kuipers and ?) are decent. As for MB, is Mette Pfeffer even still better than Florentine Rosemann from Dresden's youth? Based on their performances in junior NT last year I thought Rosemann seemed more talented overall
Pfeffer finishes school this year. So she has to leave VCO Dresden. I guess. So it's more likely Dresden will sign her. Maybe Rosemann can get a license for both leagues.
I'd say both are on a pretty same level. Pfeffer seems to be a better blocker, Rosemann a better attacker.
