CLEMSON, S.C. -- Tajh Boyd played less than a half, but that was all that was necessary.
Boyd ran for an early touchdown, then took the majority of the day off as No. 4 Clemson cruised to a 52-13 victory against South Carolina State Saturday afternoon at Memorial Stadium.
Boyd failed to throw a touchdown pass for the first time in 17 games, dating back to a loss at North Carolina State on Nov. 19, 2011, so his back-up came on and provided most of the Tigers' fireworks.
Cole Stoudt, the son of former NFL quarterback Cliff Stoudt, completed 19 of 20 passes for 143 yards and three touchdowns as Clemson improved to 2-0.
"I believe Cole could be a starter at any place in the ACC," said Boyd, who didn't play at all in the second half. "I think he proved that today."
Stoudt's performance broke the record for the highest single-game completion percentage (95.0 percent) in Clemson history, eclipsing the standard set by Woody Dantzler against The Citadel in 2000. Ironically, Dantzler was at the game, serving as an honorary captain.
"We weren't planning on using Cole as early as we did, but he was just awesome," Clemson coach Dabo Swinney said.
Boyd had the wind knocked out of him on a play midway through the second quarter. Stoudt came in and promptly completed six straight passes, including a three-yard scoring toss to Charone Peake that gave Clemson a 31-7 lead.
"We have been working on those plays all year and when you get in a groove out there, it all kind of comes with you," said Stoudt, a junior who entered the game with 14 career appearances. "It was fun."
It wasn't much fun for S.C. State (0-2), which mustered only 241 total yards, including just 86 yards rushing on 46 attempts for a 1.9 average.
"The key to the game was up front," S.C. State coach Buddy Pough said. "We wanted to run the ball, but we just couldn't block Clemson. And when we tried to pass the ball, their rush was too difficult to overcome.
"Today was a good learning experience for our team. Playing a team of this caliber will get us ready for the rest of the season."
Clemson, which is enjoying its highest ranking in 25 years, improved to 27-0 all-time against FCS opponents. It was just the second meeting between the Bulldogs and Tigers, who claimed a 54-0 decision in 2008.
Fourteen different players caught passes for Clemson, which led 38-7 at halftime. Germone Hopper and Martavis Bryant, neither of whom had a reception in the Tigers' opener, were the leading receivers, with Hopper grabbing six passes for 66 yards and two scores and Bryant corralling four passes for 87 yards.
Clemson's offense remained prolific, despite several starters seeing limited playing time. The Tigers' up-tempo, no-huddle offense ran 95 plays and amassed 512 yards. Fourth-team running back C.J. Davidson, who did not have a college carry until Saturday, was the leading rusher with 63 yards on 13 attempts.
Clemson's defense did its part, too, as cornerback Martin Jenkins had a 52-yard interception return for a touchdown and Darius Robinson followed with a 35-yard interception return of his own less than five minutes later to provide the Tigers with an early 24-0 cushion.
It marked the first time in Clemson history that the Tigers had returned two interceptions for touchdowns in the same game.
"Me and Darius were up talking all last night," Jenkins said. "People look at the secondary as the weak link on our team and it has been like that for the last two or three years. We were talking about how we needed to start changing the culture."
One bright spot for the visiting Bulldogs was senior Tyler McDonald. McDonald, who had four receptions for 108 yards and a touchdown in S.C. State's opener last Saturday, had another big game, scoring both of the Bulldogs' touchdowns on catches of 63 and 51 yards and finishing with four receptions for 138 yards.
