Yeah like them, or even the year before with The Temple team who blew out Penn State in Week 1, and started off 7-0 before losing to a top 10 Notre Dame team on a late touchdown. They also faced ranked Memphis and Houston teams before the season was over too. I'm curious to see what would have happened to them had they gone 13-0, but we'll never know.
I know BCS rankings are different from CFP rankings, but still the TCU team that won the Rose Bowl finished 3rd, and the 2010 Boise Team climbed all the way up to 4 before choking to Nevada. Maybe those teams wouldn't have made the playoff, but I want to see how a team like that would fare before I write off G5 teams completely
