Here are the margins projected for the N.D. games according to Howell and Sagarin. Howell estimates home field to be worth about 4 points this year and Sagarin 3.5 For each one, I used his own guess. I treated the Navy and Maryland as being neutral site games. I rounded to the nearest whole number:

Maryland
Sagarin: N.D. by 3
Howell: N.D. by 1

Purdue
Sagarin: N.D. by 5
Howell N.D. by 5

Michigan St.
Sagarin: M.S.U. by 3
Howell: M.S.U. by 3

Michigan
Sagarin: U.M. by 3
Howell: U.M. by 2

Stanford
Sagarin: N.D. by 3
Howell: N.D. by 1

Pittsburgh
Sagarin: N.D. by 10
Howell: N.D. by 8

Air Force
Sagarin: N.D. by 5
Howell: N.D by 2

F.S.U.
Sagarin: F.S.U. by 16
Howell: F.S.U. by 15

B.C.
Sagarin: N.D. by 6
Howell: N.D. by 5

Navy
Sagarin: N.D. by 26
Howell: N.D. by 23

Rutgers
Sagarin: N.D. by 29
Howell: N.D. by 26

U.S.C.
Sagarin: U.S.C. by 1
Howell: U.S.C. by 3

Both project 8 victories for N.D.

N.D. is actually rated as slightly stronger than both U.S.C. and M.S.U., but the home field advantage shifts the favorite. This is probably justified in the case of M.S.U., but home field (particularly in L.A.) has not made much of a difference in the U.S.C. series.

Stanford is rated as being slightly stronger than N.D. by both (in Sagarin's case it's almost dead even) but the home field shifts the favorite to N.D. Stanford, though, has traditionally played well at N.D.

Note that both of them project a fairly close game with Air Force.

Howell says that his system correctly projected about 76% of the games last year. The team ratings, of course, change over the course of the season, so the projections as to games late in the year could be quite different.
