12. 1947-50 Michigan (19-2-2)
The Wolverines gave up more points in their 1947 Big Ten opener, a 49-21 win over Northwestern, than they would in their next seven conference games combined (20). Their only losses in conference play during this run came in 1949 (a 2120 squeaker at Northwestern) and 1950 (a 7-0 disappointment in Ann Arbor against 10th-ranked Illinois). The Wolverines won three of their four titles outright, with only a 7-7 tie with 4-1-1 Ohio State to end the 1949 season giving the Buckeyes a share of the title (and a trip to the Rose Bowl).
11. 1909-11 Minnesota (6-0-1)
You can’t lose ‘em if you don’t play ‘em — the Golden Gophers posted two outright titles sandwiched around a 1910 season in which they went 2-0 in conference play to share a title with 4-0 Illinois. When they DID play Western Conference foes, the Gophers beat ‘em good, though, outscoring their league mates 218-24. Though the 1910 season comes with a bit of an asterisk, as it was the fourth of 10 seasons Michigan spent as an independent squad; the Wolverines beat the Gophers, 6-0, in the season finale.
10. 1971-74 Michigan (29-2-1)
After their 1970-ending loss to OSU, Bo Schembechler’s Wolverines rattled off 15 straight conference victories, allowing just two opponents — MSU with 13 points in 1971, and Purdue, with 17 points in 1971 — to reach double digits (while winning the Big Ten outright in ’71). That run was ended by a victory for the Buckeyes that split the 1972 title at 7-1. U-M and OSU split the 1973 title after their famed 10-10 tie that sent the conference’s Rose Bowl berth to a vote of the ADs — who picked the Buckeyes for Pasadena. The Wolverines responded with a seven-game run in ’74 in which they pounded the conference by a combined 20447 … and then lost, 12-10, to OSU to split the title again.
9. 1968-70 Ohio State (20-1)
This run by the Buckeyes virtually created the Big Ten as we know it now, or at least cemented in place the end-of-season hate between OSU and “That School Up North.” In 1968, the Buckeyes completed a 7-0 run through the conference with that saw coach Woody Hayes go for a 2-point conversion
