I suspect that Jasper still hasn't fully recovered, otherwise I'm sure she would have gotten some playing time in the last weeks like Grozer did. Jazmine White from Vilsbiburg had the same injury as Jasper and she was out for more than 4 months and is slowly returning now, and Jasper is a player who is heavily dependend on her jumping skills. Maybe we get to see more of her in the playoffs but I am sure that next season when she's back at full force she'll get her fair share of playing time.
As for Timmerman, I think she'd also be an upgrade over what Todorova showed this season, IMO she was one of the biggest disappointments of the league and I wonder how much that will become a factor during playoffs...
I agree with you on Todorova. She is a shadow of herself! She is one of the biggest disappointment of the season, both of her blocking and attacking performance is subpar
