Could be a difference in AP vs CFP committee ranking.
ESPN had LSU listed at #17 during the game if you go back and look at the game recap on their site.
Not to knock anyone on the list, but it is hard to see how Drew Morgan doesn't make the cut. If it is based on pure talent, that is one thing, but Drew has compiled 33 receptions for 484 yds and 6 TD's in a very depleted receiving corps. Top 10 in my book.
