"Substitutions: Let Coach Decide", like user BlueJaysFan said, this was the reason your PG did only play 19 minutes. Your coach decide Siarhey Sulima was the best PG to start. Better game shape and a lot better DMI. So how can you said that you would had won this game with Rimtas Kacesgis starting? You'll never know.
In fact, as BlueJaysFan wrote, he plays terrible this game with -22 score.
