From 2002-17, I crunched the numbers and it looks like this for West Virginia. On average the Mountaineers have signed 25 prospects per year with an average star ranking of 2.74 and average finish of 38th nationally.
During that span, the Mountaineers have a high water mark of 23rd in 2007 (although that was a huge class and several players didn't make it into school) and a low mark of 53 in 2006 (but that class only featured 16 signees).
West Virginia has had a top 30 class four times (23 in 2007, 27 in 2009, 27 in 2010 and 25 in 2013) and has had an average star rating of over 3.00 exactly three times before this current 2018 group (2009, 2010 and 2015) with the highest being 3.15 in 2010.
Overall, with the 2018 class included the figures are as such 25 signees per cycle, an average star ranking of 2.76 and finish of 38th nationally.
From 2002-18, West Virginia has signed two five-stars in Jason Gwaltney and Noel Devine to go along with 42 four-star prospects.
Overall during that span on the field, the record for the Mountaineers has been 138-67, with five 10+ win seasons and only missing a bowl game once in 2013.
