UAB has fired head football coach Neil Callaway. Callaway was hired at UAB in 2006, but I do not have all the data back that far to analyze FBS, I will start with the 2008 season - just in terms of their offensive, defensive and total rankings.
2008: UAB had the 85th most productive offense, the 112th most productive defense and the 112th most productive team in the nation - according to my NCAA model.
2009: UAB had the 61st most productive offense, the 98th most productive defense and the 83rd most productive team in the nation.
2010: UAB had the 62nd most productive offense, the 54th most productive defense and the 64th most productive team in the nation. (Yes, sometimes the rankings produce these odd results. If team A is barely more productive than team B on offense then team A will be ranked higher. If team B is much more productive than team A on defense then team B will be ranked higher than team A on defense and could be ranked a number of slots higher overall).
2011: UAB had the 106th most productive offense, the 84th most productive defense and the 114th most productive team in the nation (or sixth worst in the NCAA football bowl subdivision).
UAB has hired Garrick McGee, formerly the offensive coordinator at Arkansas. Arkansas has had a very productive offense under coach McGee for the two years he was offensive coordinator. In 2010 Arkansas was the #15 most productive offense in the nation and up to this point in the season, Arkansas is the #20 most productive offense in the football bowl subdivision.
