Unfortunately the replay on the Sting's 3rd goal doesn't show any enough footage to see who passed the puck to Basso so I will take your word.
As for the 3 Stars, do you really care about who gets the "Three Stars". If I am a visiting team there's no way I place any emphasis on who gets them. 3 stars are for the fans who payed to see the game. In saying that, Maxwell (stopped 35 shots and a ton of big saves to keep the sting in it), Schiefele and Yakupov were definitely the best players last night. If I were giving stars out I would've went:
1. Schiefele
2. Maxwell
3. Yakupov
