It seems reasonable to bring this up every year, particularly when our next opponent is coming off of a bye week.
Teams that get a week of rest and an entire extra week to prepare have an advantage over their opponent because their opponent didn't get the extra rest or time to prepare.
Bye weeks seem to hurt more than they help. Since 2002 (to 2010*), teams of the six BCS conferences have an overall win pct of 0.480 when coming off of a bye week. The Big Ten teams in particular struggle when coming off of a bye. From 2002-2010* Big Ten teams are a combined 17-32 when coming off of a bye. This is good for a 0.35 win pct.
Ohio State went 56-10 in Big Ten play from 2002-2010* but was 1-3 when facing a conference opponent after a bye. This includes their 2004 loss to Northwestern, their only loss to the Wildcats since 1971
Penn State and Iowa are also 1-3 when coming off of bye weeks and playing conference opponents
37 of the 65 major-conference teams have a losing post-bye week record.
Under Mark Dantonio, MSU has a 1-1 record coming off of a bye week
In 2008, they lost to PSU 14-49
In 2010, they beat Purdue 35-31
