Call a new instance of the UserSport model for each iteration.

      foreach ($sports as $sportDetail) {
        $sportsModel =  UserSport::firstOrNew(array('user_id' => $sportDetail['user_id'], 'sport_id' => $sportDetail['sport_id'] ));
        $sportsModel->position_id =  $sportDetail['position_id'];
        $sportsModel->shot =   (isset($sportDetail['shot'])) ? $sportDetail['shot'] : '';
        .
        .
        .
        .
        $sportsModel->save();
    }
