At Houston, Texas A&M and Texas Tech, Kliff Kingsbury was a chain moving wizard.
When one looks at the key offensive production stats—-QB completion %, QB combined TDs (passing and rushing), points per game, first downs, 3rd down conversion % and QBR—-the consistent production he got from Case Keenum (Houston 2011), Johnny Manziel (Texas A&M 2012) and Patrick Mahomes (Texas Tech 2015 & 2016) is astonishing.
2011 Keenum: 71.0%, 51 TDs, 49.3 ppg, 393 1st downs, 50.7 3rd down %, 174.0 QBR.
2012 Manziel: 68.0%, 47 TDs, 44.5 ppg, 357 1st downs, 54.8 3rd down %, 155.
