RALEIGH, N.C. — Clemson’s Deshaun Watson still thinks about carrying an unbeaten record into the final game of the season before losing to Alabama with a national championship on the line. The Tigers and their star quarterback are the preseason favorite to win the Atlantic Coast Conference and be positioned to return to the College Football Playoff, but there’s another team — Florida State — that enters the season with a playoff shot within reach. In fact, it’s not impossible that both teams could find themselves in playoff position coming out of a league where the balance of power is tipped heavily toward the Atlantic Division that includes both the Tigers and Seminoles.
