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.

Gone: CB Greedy Williams; LB Devin White-x; RB Nick Brossette.

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: DE Rashan Gary; LB Devin Bush; RB Karan Higdon.

Back: QB Shea Patterson; DE Kwity Paye; WR Donovan Peoples-Jones.

Gone: QB Eric Dungey; WR Jamal Custis; LB Ryan Guthrie.

Back: S Andre Cisco; RB Moe Neal; QB Tommy DeVito.

Gone: RB Trayveon Williams; TE Jace Sternberger; DT Daylon Mack.

Gone: FB Darnell Woolfolk; LB James Nachtigal; LB Kenneth Brinson.

Back: QB Kelvin Hopkins; LB Cole Christiansen; RB Kell Walker.

Back: RB Kennedy McKoy; DL Dante Stills; QB Jack Allison.

Back: S Kekoa Nawahine; LB Curtis Weaver; WR John Hightower.

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

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