Through four seasons of the College Football Playoff era, 7.5 teams per year have owned a top-four position at some point of the rankings. In 2018, that number is only five.
After the initial poll of 2014-2017, a new program entered the Top 4 in 14 of the next 21 rankings. This year has included a single change over the subsequent three weeks.
Kinda anticlimactic, huh?
No. 1 Alabama and No. 2 Clemson topped 2018's first ranking and haven't moved from their respective spots. Notre Dame opened at No. 4 and moved up when Alabama bounced LSU.
