"That is abysmal," he said, focusing on his 2-for-9 shooting from the floor.
The Colorado junior finished with a team-high 15 points in the Buffs' 63-58 victory against Wyoming at Coors Events Center. But, three games into the year, he is not happy with his offense.
"Right now, if it wasn't for free throws, I probably wouldn't be a very good player offensively," he said.
Dinwiddie has 38 points this year, 24 of them coming from the free throw line. He has made just 25 percent of his field-goal attempts (6-for-24) and is 2-for-9 from 3-point range.
In a season-opening 72-60 loss to Baylor on Friday, Dinwiddie was 2-for-12 from the floor. That, combined with Wednesday's performance in a close game left him "frustrated."
"It's a matter of I feel like I'm letting (the team) down by having subpar shooting performances," he said. "I feel like my percentages are what is keeping (the opponents) in the game.
"Personally, I just feel like for our team to be the best that it can be and for it to reach its potential, me, and also (Askia Booker), are going to have to be efficient. I can't control Ski, so I get mad at myself.
"The only time I get really frustrated is when I feel like the other team is in the game because I'm missing shots."
Dinwiddie did help the Buffs by hitting 10-of-13 free throws and pulling down seven rebounds.
Boyle did not utilize his bench much, as each of the five starters -- Booker, Dinwiddie, Wesley Gordon, Xavier Johnson and Josh Scott -- played at least 30 minutes.
Six players came off the bench, but combined for just 43 minutes of playing time. Xavier Talton had 16 of those.
CU's four true freshmen -- Tre'Shaun Fletcher, Jaron Hopkins, George King and Dustin Thomas -- combined for just 25 minutes, just nine of those in the second half.
"That's the way it's going to be until we get these freshmen some time," CU coach Tad Boyle said. "Our freshmen are going to be good, every single one of them. I promise you. But, it's going to take some time."
The freshmen averaged 49 combined minutes in the first two games.
Talton had his most extensive playing time since getting 20 minutes against Northern Arizona early last season. He was in the game in the final minutes.
"I didn't want to put a freshman in that situation," Boyle said. "He's a good defender, I've got confidence in him. We wanted to go with a defensive lineup."
Stopping the 3
Through two games, one of CU's concerns was its 3-point defense. The Buffs gave up 20 3s in the first two games.
Then, in the first half, Wyoming went 5-for-10 from beyond the arc. CU buckled down in the second half, though, as Wyoming went 2-for-11.
Boulder High graduate Riley Grabau finished with nine points and five assists for the Cowboys. He fouled out in the final minutes but led all players with 38 minutes played.
"It was good. I got to see a lot of family and friends," he said. "It's fun to play in front of the city of Boulder."
A junior, Grabau has started both games this season and is averaging 13.0 points and 4.0 assists.
"Wyoming is good. I think it's the right fit for me," he said.
CU is 46-7 at home under Boyle. ... Scott has led the team in rebounds all three games. He had nine on Wednesday. ... CU will host Jackson State on Saturday at 10 a.m.
