Give over man.
How did Dreher not bring their "game"? Both teams brought it and since Riverside is better it just seems as if Dreher didn't because Dreher couldn't do what they wanted to since Riverside had control most of the time. I mean it's not like Dreher just gave the ball away all the time. When they had it they did well with it but Riverside had the ball more often than not and they also moved it around well. Bottom line is that both teams brought their game and the superior "game" was victorious. On another note, the defenders may have not brought their game because WOW they got megged like 8 times.
If the throws are a key asset on scoring then you probably need more than like four throw-ins to score a goal even if you could get it in the box, so that is actually what reduced the opportunities by a third. Dreher didn't have many opportunities to use their throws because they didn't get into the attacking third a whole lot. And if the throws don't work why not throw to someones feet and then serve it in.
