And Blackmon followed through by contributing in a big way as the No. 19 Cowboys rolled No. 22 Baylor 55-28 in his first game after serving a one-game suspension for a DUI.
During the game, in which Blackmon caught 13 passes for 173 yards and touchdown to go with one carry for a 69-yard score, Baylor coach Art Briles noticed something about the Ardmore native, as well.
"He's a stud," Briles said.
It didn't take long for Blackmon put his impact on display as he hauled in an over-the-shoulder touchdown in the back right corner of the end zone for the first touchdown of the day. He finished the first half with eight receptions for 115 yards as OSU led 24-0 at the break, matching the team's game total from the victory at Kansas State in his absence.
On the first play of the second half, it was Blackmon who surpassed last week's total when he took a Brandon Weeden pitch on a reverse to the house.
"They had 11 guys running one way and we had Justin running the other," Weeden said. "When he's in the open field, I like my chances."
Offensive coordinator Dana Holgorsen said he didn't know what to expect from Blackmon from a production standpoint in his return but he said he knew who the best player on the field was as the Cowboys improved to 8-1 on the season and 4-1 in Big 12 play.
"You can tell who the best player on the field is on game day," Holgorsen said. "You can't tell that on film, you can't tell it going in but you can tell it on game day and there hasn't been a game go by where I haven't felt like he is the best player out there."
And having the Cowboys' best player back in the fold helped Weeden set school records for passing yards (435) and completions (34), en route to a school record 725 yards of total offense.
"(Having Blackmon back) is just the security of your last read more than anything," Holgorsen said. "Brandon knowing that he is there. For me, calling plays is easier because if their safeties are playing hard then we can get it down field. He is a great player. He finishes things, he attacks the ball on third down."
Weeden said he was even happier for Blackmon to be back on the field than he was to have him as a target.
"He is such a good guy. He knew he made a mistake, but he was ready to come back and play this week," Weeden said. "He can really stretch the field vertically.
"He is dangerous and I was glad to have him back."
