Not surprisingly your rants are not based on fact.
http://www.somersetrebels.co/news.php?extend.640 confirms that Monberg comes in on a 7.67 average, well above Lanham's current Green Sheet average.
Try again.
Under the new Green Sheets he could only have replaced Doolan or Tungate. I believe Leicester away on Saturday was the cut of for the new averages.
Bad timing?
Assume this is typical Evening Star dramatic headline of this story...
