I think, that Schwerin was once more vulnerable especially in the head: the statistics of Schwerin were not that bad, but they started bad in first and fourth set and couldn't get managed the crunch time. Of course Bursa has the advantage to play in a much stronger league than Schwerin, who has only one truely (nearly) equal opponent in Germany (Stuttgart), while Bursa plays lots of matches in the season against powerhorses like VakifBank, Fenerbahce, Escacibasi or at least nearly equally strong opponents like Canakkale. Anyway, to win with three points in Bursa is kind of mission impossible for Schwerin, the chances are heavily on Bursas part at home...
Studying statistics confirmed my view: main issue was, that Schwerin made way too many errors (34 compared to 25 of Bursa), so despite serving better (6 aces more) and receiving better didn't help them. Attack efficiency was also in favor of Bursa (44% to 40%), partly due to making more errors in attack too (see above). This is quite unusual, because in German league Schwerin is very constant and making few errors usually - hints to a not sufficient mindset of them today.
