Deion Sanders made sure to let everyone know after Colorado upset No. 17 TCU on the road Saturday that he kept receipts.

The Buffs were one of the hardest teams in the country to peg coming into the new year. With more than 80 newcomers — more than 50 of which were transfers — and a head coach that was making his FBS coaching debut, no one knew what to expect.

Some thought Colorado would struggle just like it did a year ago, when it limped to a 1-11 record. Some thought Colorado could be feisty.

Very few thought the Buffs, as a 20.5-point underdog, would walk into Fort Worth and do what they did to the Horned Frogs. Sanders and his crew topped 500 yards of offense to win 45-42.

“What we accomplished out there today, ain’t none of y’all believed that,” Sanders said in the postgame. “Maybe a couple of y’all that knew me and know how I get down. They know I’m a winner. We’re gonna end up winning.

“Ain’t none of y’all thought we’d be sitting up here. You was supposed to be on the other side interviewing them and coming and asking me, ‘Well, what happened? You said this and you said that.’ Yeah. And now what? Now what? Everybody quiet now. Now what?”

Colorado and TCU traded scores all throughout the second half on Saturday. The lead changed hands six times over the game’s final 18 minutes.

But CU kept answering each TCU score with points of its own. And the defense got a stop when it needed it on TCU’s final possession.

The “us against the world” mentality was a common theme throughout Coach Prime’s postgame presser.

At one point, Sanders interrupted a reporter before they could get a question out.

“Do you believe now?” Sanders asked. “Huh? I read through that bull junk you wrote. I read through all that.”

When the reporter asked if they could ask their question, Sanders asked back once again if they believed. When the reporter responded, “believe what?” Sanders laughed and said, “Next question.”

Sanders has faced doubters and critics since he took the Colorado coaching job. He was more than a little defiant following the Buffs’ statement win.

“We’re gonna continuously be questioned because we do things that have never been done,” he said. “And that makes people uncomfortable.

“When you see a confident Black man sitting up here and talking his talk, walking his walk, coaching 75% African-Americans in a locker room, that’s kind of threatening. Oh, they don’t like that. But guess what, we’re gonna consistently do what we do because I’m here and I ain’t going nowhere. I’m about to get comfortable in a minute. I’m about to get comfortable in a minute.

“Guess what. These young men in there right now, they believe. Not all of them believed before. But right now, they came up one by one, two by two, ‘Coach, we believe.’ Now they believe. Now Boulder believes. People in the front office, people in the building, the fans, the students, now everybody wants to believe. I’m good with that. We’ve got room.”
