Below is a chart of the University of Maryland's offense, defense and total production rankings since 2008 along with the rank of the worst team in the Football Bowl Subdivision during the time period. As you can see the Maryland Terrapins have not been above average except for the last season with Ralph Friedgen as head football coach since 2008. More information from the model is presented below.
2008
Unfortunately, I do not have all the data to run the model before the 2008 season, so I am unable to show how Maryland performed in the previous seasons with head coach Friedgen. As such, I can only evaluate based on the data that I have and the model that I am using is the same since the 2008 season. That said, Maryland finished the 2008 season at 8-5 and bowl eligible and played against an "average" strength of schedule (SOS) as compared to the "league" average, meaning that their actual SOS was within one standard deviation of the "league" average SOS. Maryland's best game was a victory over #14 ranked California and their worst loss was to #85 ranked Virginia. Overall, the Terrapin's had the #70 most productive college football team with the #77 ranked offense and the #62 ranked defense.
2009
Statistically this was Ralph Friedgen's worst team during this time period. Maryland finished the regular season at 2-10 and played against an "average" strength of schedule (SOS) as compared to the "league" average. The Terrapins's best game was a victory over #10 ranked Clemson and their worst loss was to #96 ranked Virginia. Overall, the Terrapin's had the #107 ranked team in terms of total production with the #105 ranked offense and the #80 ranked defense.
2010
Maryland significantly improved their production in this season finishing at 9-4 while playing against a "average" strength of schedule (SOS) as compared to the "league" average. The Terrapins's best game was a victory over #32 ranked North Carolina State and their worst loss was to #56 ranked Clemson. Maryland finished the season with the #28 ranked team in overall productivity with the #45 ranked offense and the #21 ranked defense. Unfortunately, this was not enough for Ralph Friedgen to keep his job as head football coach at Maryland.

Maryland hired Randy Edsall away from the University of Connecticut during the Summer of 2011. In Edsall's first season as head football coach the Terrapins finished at 2-10.
