There's something people miss - Saraf is barely 19 y/old and high level pro-team is heavily dependent on him. Even in previous game which was really really bad one - Ulm's coach still sent him back to court with 4 PF 3 min to the end of the game... And he took two shots in last minute and half, and missed both, so we can say "here he failed" but maybe more important is that he was confident to take those shots, and his coach was confident in him to give ball in his hands in decisive moments (and the team led in this way by Saraf finished 2nd in G-BBL and reached final)
Here's by the way final series poster on G-BBL site:

p.s
Maybe it's a bit disappointing that Saraf (and Essengue) will not be available for work-outs... but they are going into series against above average EuroLeague team, maybe it will give even more clues.
