A lot of things could happen. 3 and 9 is could happen, but to say it is probable takes some evidence. Questions about the defense are not evidence. Many people make the mistake of assume that if we don't know something, that lack of knowledge counts as evidence. Weber could have another bad year or it might not be so bad with a sane offense.
What we don’t know:
Exactly how the 2010 team will perform.
What we have evidence of:
Offense
The offense has been ranked at #11 offensively in conference play for the past two seasons.
Offensively, the difference in Time of Possession was a decrease of :24 from ’08 to ’09. The ‘09 defense did not spend significantly more time on the field.
Offensively we scored more points per game in conf. play than we did in 2008
We gave up 8 more sacks, or one per game in 2009 (29 vs. 21)
The running game improved by nearly 20 yards in 2009, but still ranked #11 in 2009 (as it did in 2008)
Defense
The Defense was on the field for 561 plays in 2009 vs. 534 plays in 2008. Effectively they were on the field for roughly 3.5 plays more per game in 2009.
The Defense gave up 5 fewer yds/game in conf. play in 2009
Defensively we gave up .6 points per game more in 2009– effectively the same as the year before
3rd Down conversions went from opponents being successful 39.4% in 2008 to opponents having a 49.2% success rate against us in 2009
Red Zone defense went from #1 in the Big Ten in 2008 to #9 in 2009.
Special Teams
The return games was #5 in KO returns (down from #3 in ’08 but with more yardage in ’09) and #1 in Punt returns (up from #7 in 2008)
Punting improved to #2 in the conference from #5
Discipline
In 08 we were #10 in the Big Ten in penalty yards/game with 56.5. In 2009 we were #9 in the Big Ten with 57.4 yards/game.
NOTE: The above numbers are influenced by switching out Michigan for Michigan State and Penn State for Indiana. While there are significant statistical differences between the four teams, the record in each season was the same: 1-1.
ADDITIONAL NOTE: All stats are for Conference play only.
Evidence vs. Opinion
The evidence is historical, but there is significant evidence that the pre-season rags aren’t wrong. I hope that things get much, much better, but there isn’t evidence to suggest it will. I will continue to hope, but my analytical nature suggests that my hope will not be rewarded again this season.
