Let's keep in mind the level of competition difference between year 2 of McFarland (2008) and year 2 of Herman (2010).
2008 was a year of inflated offensive statistics across the board in the Big XII. Oklahoma (#3), Texas Tech (#4), Oklahoma State (#6), Missouri (#8), Texas (#9), Nebraska (#12), and Kansas (#21) were all in the top 25 nationally in total offense. There wasn't a single Big XII team in the top 25 in total defense. The highest rated defense was #51 Texas. There was likely many bad defenses in the Big XII that year.
The best team we played was 9-4 Iowa or 10-4 Missouri. We faced 5 bowl-eligible teams.
2008:
South Dakota State
Kent (4-8)
@Iowa (9-4)
@UNLV (5-7)
Kansas (8-5)
@Baylor (4-8)
Nebraska (9-4)
TAMU (4-8)
@OSU (9-4)
@Colorado (5-7)
Missouri (10-4)
@KSU (5-7)
In 2010, offenses in the Big XII aren't nearly as prolific. Oklahoma State (#2), Baylor (#8), Oklahoma (#17), TAMU (#18), and Nebraska (#24) rank in the top 25 nationally in total offense. There are currently 2 defenses in the top 25 nationally in total defense. Texas (#4) and Nebraska (#9).
We have only played one team that currently has a losing record (UNI), and I think the 6 FBS teams we've played will all make a bowl game this year, as will at least 3 of the remaining 5, for 9 or 10 bowl teams this year. We are playing 4 teams that potentially could make a BCS bowl (Iowa, Oklahoma, Nebraska, and Utah).
2010:
Northern Illinois (5-2) [probable finish 9-3 or 10-2]
@Iowa (5-1) [10-2 or 11-1]
KSU (5-1) [7-5 or 8-4]
UNI
Texas Tech (3-3) [6-6 or 7-5]
Utah (6-0) [11-1 or 12-0]
@Oklahoma (6-0) [11-1 or 12-0]
@Texas (4-2) [8-4 or 9-3]
Kansas (2-4) [2-10 or 3-9]
Nebraska (5-1) [9-3 or 10-2]
@Colorado (3-3) [5-7 or 6-6]
Missouri (6-0) [9-3 or 10-2]
IMO, our offensive production under Herman has not been good, but probably about what should be anticipated to this point given the level of competition we've faced.
