Six Atlantic Coast Conference teams are undefeated entering this weekend, so it’s no surprise that the matchup between Clemson and Syracuse features one team with an unblemished record.However, in an unlikely twist, it’s the host Orange who will put their unbeaten mark on the line Saturday.Clemson (2-2, 0-2 ACC) outgained then-fourth-ranked Florida State 429-311 last weekend and outrushed the Seminoles 146-22 before falling in overtime 31-24. Clemson committed a costly turnover and also missed a 29-yard field goal in the disappointing setback.”That, honestly, was probably as tough a loss as I’ve ever been a part of,” Tigers coach Dabo Swinney said, adding that “if you can’t see the heart of our team, then you’re just blind.”An agitated group of Tigers will travel to Syracuse to take on the Orange (4-0, 0-0), who ran the table in non-conference play, punctuating the slate with a 29-16 triumph against Army last week.Syracuse survived a sluggish first half in which it trailed 10-3 at intermission before scoring the first 26 points of the second half.
