Definitely a lot of optimism there. Defense has a "B" overall grade and Offense has "B-" grade. Overall grade of a weak B seems about right but is a best case scenario.
"A" teams on the schedule (hope for not being blown out):
Wisconsin
Michigan
"A-" teams on the schedule (hope to appear somewhat competent in a lopsided loss):
Iowa
Nebraska
"B+" teams on the schedule (hope for an upset, although unlikely)
NW
Mich State
"B" teams on the schedule (hope for a competitive game):
Purdue
"B-" teams on the schedule (Illini win or lose faith):
Minny
Rutgers
"C+" teams on the schedule (If Illini lose, time to panic)
EMU
UConn
Akron
Path to 6 wins involves consistenly playing up to a "B" grade and beating Purdue, NW, or Michigan State.
