A couple things stood out to me. One is Indiana's 3-0. Their first-ever appearance at #1 came after beating the Buckeyes in the last B1GCG and they then won three games in the CFP. The other is the teams that are 0-fer as #1. That just sucks. To get all the way to the mountaintop then then immediately fall sucks. So here they are:
Boston College:
The Eagles only have one appearance at #1 and only two at #2. They have 16 top-5 appearances and have been ranked in 145 of 1,267 polls (11%). Not only are they 0-1 as #1 but it was a BAD loss. They started 1942 at #11 and an 8-0 start got them the #1 ranking in the November 23 AP Poll after #1 Georgia lost at home to unranked Auburn. Then they got obliterated (55-12) by unranked Holy Cross in Boston and for good measure they also lost the Orange Bowl badly (37-21) to Alabama.
SMU:
The Mustangs have two appearances at #1 and five at #2. They have 30 top-5 appearances and have been ranked in 197 of 1,267 polls (16%). They only have two appearances at #1 because they took the week off after attaining the #1 ranking. They started 1950 at #10 and beat GaTech and #11 Ohio State before the next poll came out. At that point they were 2-0 and #3. Then #1 (ND, at PU) and #2 (MSU vs UMD) both lost and SMU moved up to #2. A 42-21 win over #15 Rice on October 21 moved them up to #1 and then they took a week off and remained #1 in the 10/30 poll. When they returned to action it was ugly. They lost 23-20 at Texas as #1 then lost 25-20 at home to aTm the next week as #7. The ended the 1950 season 6-4 and unranked.
Wisconsin:
The Badgers have one appearance at #1, seven at #2, and 49 in the top-5. They have been ranked in 416 of 1,267 polls (33%). They opened the 1952 season at #7 and fell a spot for "only" beating Marquette 42-19. Then they knocked off #2 Illinois 20-6 while previous #1 (MSU) struggled with Oregon State (17-14 win). That moved the Badgers all the way up to #1 in the October 6, 1952 poll but that Saturday they lost 23-14 in Columbus to an unranked Ohio State team that had a young upstart named Woody Hayes in his second year as HC. Wisconsin did end up winning the BigTen that year and lost the Rose Bowl to #1 USC.
Missouri:
The Tigers have two appearances at #1, two at #2, and 23 in the top-5. They have been ranked in 292 of 1,267 polls (23%). Unlike SMU who got their second #1 appearance by having a week off, the Tigers have reached #1 on two completely separate occasions and they immediately lost both times:
In 1960 the Tigers started unranked but won their first nine games. The ninth win was over Oklahoma as #2 and the previous #1 also lost that week (MN to PU) so the Tigers got the #1 spot in the November 14, 1960 poll then lost 23-7 to Kansas and finished the season #5.
In 2007 the Tigers started unranked but started 5-0 to climb to #11. Then they lost 41-31 at Oklahoma but Oklahoma was #6 and it was a road loss so the Tigers only dropped to #15. They then proceeded to win six straight including over #2 Kansas on November 24. Conveniently for #3 Mizzou, #1 LSU lost 50-48 to Arkansas in 3OT that same day which opened the way for Mizzou to claim the #1 spot for their second time. Unfortunately for Mizzou their next assignment was a second crack at the Sooners, this time in the B12CG. That didn't go any better than Mizzou's previous shot at the Sooners with #9 Oklahoma winning 38-17 over #1 Mizzou. That same day #2 (WVU to unranked Pitt) lost which paved the way for Ohio State to regain the #1 ranking.
