FORT WORTH, Texas - TCU had its share of questions after slipping past Minnesota the previous week, but they looked much more like the nation's third-ranked team Saturday night.

Trevone Boykin passed for four touchdowns and Aaron Green ran for two more as the host Horned Frogs blasted Stephen F. Austin 70-7 on Saturday at Amon Carter Stadium.

A week earlier in a 23-17 win at Minnesota, Boykin struggled to find any rhythm, and the defense suffered a series of personnel losses.

None of that mattered Saturday against an overmatched FCS foe from the Southland Conference. The Horned Frogs had more touchdowns in the first quarter against the Lumberjacks than they did in the entire first game and piled up 627 yards of offense.

"We wanted to get better in some areas, and we got better in our special teams groups," TCU coach Gary Patterson said after his 14th consecutive home-opening win. "We got to play a lot of players."

Boykin didn't miss the open receivers he over-threw against the Golden Gophers, finishing 18 of 27 for 285 yards and one interception. The Heisman Trophy candidate completed passes to seven different receivers before hanging it up for good after one series in the third quarter.

"It's a fast-paced offense but me and (center) Joey (Hunt) have complete control of the tempo of the game," Boykin said.

TCU receiver Kolby Listenbee hauled in two passes of at least 51 yards, including a touchdown, and finished with six receptions for 142 yards.

Despite the gaudy offensive numbers, Patterson sees room to grow for a team that expects to be in the national-championship hunt.

"We still got a lot to improve on," he said. "I thought we started very slow. You've got to come ready to play. Nothing is going to come easy. I didn't feel like today was easy for them."

The Lumberjacks (0-2) finished with only 167 yards of total offense. SFA had 15 yards on its first play from scrimmage before managing only 24 yards on its next 36 snaps going into halftime.

The talent difference was obvious.

"I guess now these games are part of the landscape in college football for FCS schools," SFA coach Clint Conque said. "They have a tremendous program here at TCU. I thought our kids competed the best that they could. We are pretty depleted right now, but at the end of the day, they have an outstanding football team with outstanding athletes."

SFA quarterback Zach Conque completed 11-of-18 passes but for only 9 yards. Conque was sacked four times and picked off once. Backup quarterback Hunter Taylor (2 of 10, 12 yards) came on for the second half.

The Lumberjacks (0-2) had a chance to strike first thanks to a 14-yard punt on the Frogs' first possession. SFA drove inside the TCU 10-yard line but elected to bypass a short field goal attempt with its starting kicker was out and go for it on fourth down.

The Lumberjacks came up short, and the Frogs didn't need long to take the upper hand. Two long Boykin throws helped TCU cover 93 yards in eight plays.

Green took it the final 2 yards for the game's first touchdown. The senior added another TD later in the first quarter on a 7-yard scamper.

Boykin's first scoring throw was a 60-yard bomb to Listenbee with about two minutes left in the first quarter and the rout was on. TCU took a 35-0 advantage into halftime.

"We were outmanned from the get-go," Conque said. "We knew it'd be a tough day, but we had a couple of opportunities, got in the red zone a couple of times, and came away with no points.

"We don't have a kicker right now, which is why we didn't try field goals. I'm not making any excuses at all, but we came away with no points there and gifted them a few turnovers, which you can't do to a great team."

Boykin connected with receiver Emmanuel Porter from 3 yards and called it a day early in the third quarter. TCU also scored on safety Denzel Johnson's 50-yard interception return before backup quarterback Bram Kohlhausen led two late touchdown marches.

The shutout was spoiled less than a minute in the fourth as SFA freshman running back Loren Easly broke a 75-yard touchdown run up the middle.

The Frogs look to make it 3-0 next week as neighboring rival SMU visits Amon Carter Stadium. TCU has won 13 of the last 15 meetings.

Stephen F. Austin opens Southland play at home next week against McNeese State.
