But ESPN seems to think that one team on the Tigers’ 2019 schedule could give them a run for their money.According to ESPN’s Football Power Index (FPI), Clemson’s September 7 home game against Texas A&M is the hardest game on the schedule. The Aggies finished with a 9-4 ranking and were No. 16 in the final standings last season.The game will also continue the coaching rivalry between Swinney and Texas A&M head coach Jimbo Fisher, who previously served as head coach of the Florida State Seminoles. Under Fisher’s guidance, FSU beat Clemson in three straight games from 2012 to 2014.Last year, Fisher and Swinney faced off at Kyle Field, but Swinney got the better of the matchup with a 28-26 win that came down to a failed two-point conversion attempt. Beating the Tigers at Memorial Stadium is a tough ask though, even for a team as talented and well-coached as Texas A&M.Clemson has lost only once at home since 2014 – a 43-42 loss to Pitt in 2016.Prior to that loss in 2016, Jimbo Fisher’s FSU was the last team to beat the Tigers at Memorial Stadium – a 51-14 blowout win in 2013.
