The Frogs advanced to 1-0 with a 53-46 victory over Cal Poly.
"The good thing is we won," Trent Johnson said. "As a group, we're not satisfied with the way we played. We've practiced a lot better. One of the things I addressed to them is we're going to be in our share of close games this year, and finding ways to win is important."
"It takes time. Rome wasn't built overnight," Johnson said.
The Mustangs took a one point lead into the locker room at halftime as TCU shot just 36.4 percent from the floor in the first 20 minutes.
Amric Fields led the TCU offense in the first half with 10 points.
In the second half, TCU took the lead at the 17 minute mark and never trailed again. The Mustangs kept the game close and trailed by just one point with two minutes remaining.
Amric Fields once again came up big for the Frogs as he put TCU back up by three with a hop step into the middle of the lane and a floater.
From there, TCU made enough free throws to close out Trent Johnson's first game with a seven point win.
"I might add this," head coach Trent Johnson said. "There is a disposition about this group that I really like, and that's important."
Johnson said he was not happy that his team got out-rebounded at home, and he said his team missed too many shots that they should have finished in the lane.
"Everything for these [players] is new. New teaching, new system, and I'm getting accustomed to them as much as they're getting accustomed to me," Johnson said. "It's the defensive end of the floor that we have to do better. We gave up way too many easy baskets."
While Johnson and his players felt they gave up some easy baskets, the Frogs still held Cal Poly to just 35.2 percent shooting for the game.
Cal Poly kept the game close with bench scoring and second chance points. The Mustang bench outscored TCU's 18-5, and TCU's bench was outscored 18-4.
Anderson, Fields and Green started along with junior Jarvis Ray and senior Adrick McKinney. Johnson was pleased with McKinney's performance after the game.
"Adrick did a good job. He has quite frankly outplayed Devonta over the last week in practice, and for Devonta and Adrick, they have been struggling a little bit. They will get better as we move forward," Johnson said.
McKinney finished with five rebounds on the night and gave the Frogs a strong defensive effort.
The win for Trent Johnson meant that the last six TCU coaches have now opened their tenure's at TCU win a win.
The Frogs are also 15-3 in their last 18 home games.
"Any W is a good W," senior Garlon Green said. "I think we have a lot to work on. Hopefully it will happen faster than even we say."
Johnson said the only thing that matters for his team is playing well.
"All that matters is that you play well, and you play the game right," Johnson said. "We're going to be as good as we can be this year, and whoever beats us, they're gonna beat us because they were better that day. It won't be because of lack of effort."
TCU will play another home game on Monday evening versus Centenary. The game is set to tip-off at 5:00 p.m.
