RV coach Dean Norris said, "Although we shot the ball better tonight , we put ourselves in such a hole with the turnovers that it made it difficult to win the game."
On a positive note, continued the veteran coach, "The kids' attitude and effort remain positive, and we did shoot 16 for 20 from the free throw line."
The busy River Valley boys host Marcus-Meriden-Cleghorn here tonight, play at Remsen-Union Tuesday night, and host Alta-Aurelia Thursday night, and Westwood Friday night.
