Clemson beat Alabama for the national championship, but can the Tigers keep the Crimson Tide from reaching another less significant milestone?

Alabama has been preseason No. 1 in the AP poll the last three seasons, matching a record held by Oklahoma, which started No. 1 each season from 1985-87. Another preseason No. 1 in 2019 would make Alabama the first team to ever start four consecutive seasons top-ranked since the preseason poll started in 1950.

Clemson has never been preseason No. 1, but maybe next season.

At the very least expect a second straight season of the Tide and Tigers holding the top two spots to start the season in some order as both teams return star quarterbacks and a bevy of weapons.

The final 2018 rankings were revealed a few hours after Clemson beat Alabama 44-16 Monday night in the College Football Playoff championship game. The final Heat Check of the season looks at how the teams in the final rankings might start next season.

Back: S Grant Delpit; CB Kelvin Joseph; QB Joe Burrow.

Gone: DE Jachai Polite; S Chauncey Gardner-Johnson; RB Jordan Scarlett.

Back: QB Feleipe Franks; S Brad Stewart; CB C.J. Henderson.

Gone: QB Jake Browning; LB Ben Burr-Kirven; S Taylor Rapp.

Back: QB Jacob Eason; OL Trey Adams; WR Ty Jones.

Gone: TE Noah Fant; S Amani Hooker; DL Parker Hesse.

Back: QB Nate Stanley; DE A.J. Epenesa; TE T.J. Hockenson.
