This is embarassing for Vakifbank. 😭

How's Ajcharaporn doing in Japan?

According to Turkish media, Robert Ratzke will join Turk Hava Yollari Spor Kulub from the new season.
she might be the starter for Brazil NT next season or Coach Ze has enough faith in Macris to let her play on other team.

Roberta Ratzke to THY
Bergamann is staying
OMGGGG I HAVE BEEN WAITING FOR HER TO PLAY IN TURKEY OR ITALY!!!

Roberta Ratzke will play in Turkey from next season?
I would love this. Wish she goes to Vakifbank when Gabi is still there. 😂

I honestly believe that Bernardinho is the best in the game when it comes to developing players. When you look at Sesc's current line-up, you see a lot of players who were once considered to be average/mediocre and are now playing very well: Laís (the best Brazilian libero after Brait IMO), Valquíria, Sabrina, Brie King. Roni Jones-Perry's passing and defense has also improved a lot.
Kosheleva also got some of his magic touch.

Gabi is the only one scoring double digits on Vakifbank in a 4 sets match. 😂
-
I don't know what will happen to Vakifbank next season when Gabi leaves.
-
This match is a mess.
-
Gabi is doing everything she can while this team......

Gabi + Zhu was always one of my dream pair. Gabi + Haak reunion is always something I am waiting for. But to have Gabi + Haak + Zhu on the same team? It is time to subscribe to the league youtube channel.

Display MoreHuge offtopic, but...
These rankings on dataproject websites are traditionally messy, because they overestimate the relevance, for example, of serve numbers and blocking in overall index of the players. I've analyzed it (in context of male volleyball) already and this is a continuous trend. Bergmann is great in both figures, so it's for me a no surprise that she's pretty high on such list even though her offense is pretty mediocre.
And I was analyzing it, because during the Christmas break I got sick, so I had much more time than I needed/should have had - so I'd decided, but again, it was in context of male volleyball (have no time to analyze female vball in that detailed way in the past few years), to make my own performance rating calculations. I came to the conclusion that the best way to do it, and I've started with OH players of Polish/Italian league - is to, first, estimate league averages in every element (serve, blocking, attack, reception) for starter-level players (and some back-ups with the highest number of reception/attack attempts), and then, to compare each player's stats vs league averages to estimate their performance rating as a sum of standard deviations with specific weights (I went for weights with '1' for blocking, '2' for service, '3' for reception and '4' or '5' for an attack - again, it was made for male volleyball-driven analysis) vs league averages.
I'm saying it all because it turned out that such pretty simple, even rudimental, analysis turned out to be pretty decent. The formula for every player is:
blocks/set / league average * 1
(((aces/set / league average in aces/set *0,3) + (serves/set / league average in serves/set) *2) *2)
(((positive reception / league average in pos. rec. + perfect reception / league average in perf. rec.) / 2) * 3)
((((spike efficiency / league average in spike efficiency)+ (kills rate / league average in kills rate) + (attacks per set / league average in attack per set) / 3) * 5))))
The biggest problem of this formula is that it devalues 'role players' often subbed in/subbed out (because it's based on per set basis), but for starter-level players - in context of male volleyball - it gave results pretty much corresponding to the eye-test, because it takes into account most of the measures that we know as fans from statistical standpoint.
It even allowed me to make very quickly a 20-year performance rating ranking for OHs from Italian leagues which, once again, was pretty much in line with what the one could have expected (Juantorena and Leon being the best in this span with several outlier seasons). To be honest, I was quite proud of this because this 'vs league averages-analysis' allowed me to compare different eras of volleyball (as, for example, lower level in attack rate was represented by lower league averages). You have to take it with a grain of salt, but it was fun to do such analysis.
The point is - within different formula, it is doable in context of female volleyball as well, I believe, to make such rankings, although the question is what would be the weight the one agrees to assign, because obviously, quantitative analysis in such field are in fact mixed quanti- and qualitative analysis, really, as these weights are pretty subjective.
The biggest problem that I find is that reception stats from female Italian league, for example, are messy, because I copy-pasted the stats from legavolleyfemminile.it (the same template as from male league) to Excel and I highly doubt that Cazaute is the best receiver, Herbots is the 3rd-best and Piva, Daalderop and Sylla are 8th-10th best, from what I remember them from the last season.
Re: Turkish league, I took dataproject data and adjusted the aforementioned men-oriented formula with weights of 4 for reception and attack (assuming in female volleyball there's more of parity in this characteristics), and this is what I got:
Name Rating BRAGA GUIMARAES 7,06 FEDOROVTSEVA 4,91 MARKOVA 4,70 FRANTTI 4,08 WILHITE 3,77 AYDIN 3,24 VORONKOVA 3,03 LEE 2,99 BERGMANN 2,86 VASILANTONAKI 2,49 GRAY 2,29 DIMITROVA 2,13 BEGIC 1,77 BALADIN 1,73 SENOGLU IVEGIN 1,50 KUNZLER 1,12 DIKEN 1,08 GUERRA 1,02 BUSA 0,95 ARSLAN 0,09 BEKTAS -0,71 EGGLESTON -1,01 CAFFREY -1,06 MILENKO -1,08 LODA -1,09 LEYVA TAGLE -1,58 MICAYA -1,60 TANYEL -1,76 SEKERCI -1,88 BASCAN -2,12 HACIMUSTAFAOGLU -2,21 URAL -2,57 LEBAN -2,79 FIRINCIOGLU -3,29 DURGUN -3,40 YORDANOVA -3,51 SALAS ROSELL -3,51 NEZIR -3,62 TECIMER -3,89 AKMAN -4,57 DEMIDOVA -5,57 The highest values for men players were ~5 in Italy/Poland, but I guess Gabi's numbers are such an outlier due to the bigger disparity in level of female Turkish league (what results in lower league averages and her stats being the bigger statistical deviation vs stats of Leon or Juantorena). Obviously, 'positive' means statistics of player X being overall above league average and 'negative' being below league average.
Like I said, you have to remember that players more often subbed in/subbed out will have their value 'deflated', but regarding the very top, it's obviously much more telling than these dataproject ranking and probably in line with an eye-test.
ps
Obviously, I'd be glad to move this post to another thread, I just thought this feedback may be interesting for some people, sorry for going off the road with such post as this is transfer topic.
Thank you for this input. But can you explain more on why Gabi's number is so far compared to the others?

Fenerbahçe
what an honour.
-
OT: saw on Twitter that they are building Eda's statues. Is it for Fenerbahce or the NT?
-
Plummer in Turkey ❤️ Hande gonna be doing heavy duty in receiving but Plummer adds on fire power for them
-
Scandicci is interested on bajema/ or Frantti to replace zhu. I thought vakifbank renewed Frantti? Or maybe they will go with Bosetti or plummer next season
Zhu to Vakifbank? 😂
-
Read on Twitter that there are rumors that Roberta is negotiating with a team from Italy. Is there any ring of truth to it?
-
The thing that Chiaka did in that match is just... 😨
Finally I got to see that "well-oiled machine" that Vakif is known for. -
Atlanta VS Omaha is kinda full house. Good start for the league!
