Lillard scored a career-high 60 points for Portland in the Trail Blazers' 119-115 loss to the Brooklyn Nets on Friday night.
''He got 60, but luckily for us he would of needed 65,'' Dinwiddie said of Lillard after the game.
Lillard set a franchise record with the highest-scoring game of the season in the NBA. He was 19 of 33 from the field, 7 of 16 from 3-point range and made all 15 of his free throws.
''We tried zone, box-and-one, we tried blitz, we threw the kitchen sink at him,'' Nets coach Kenny Atkinson said of Lillard. ''He just kept making incredible shots.''
''It's fine,'' Lillard said about his 60 points coming in a loss. ''It's whatever. Anytime you set records it's obviously good. I guess it's not as fun losing.''
Irving, the NBA's second-leading scorer coming in to the game, did his part in the guard matchup for the Nets. He had nine fourth-quarter points and hit a shot to put the Nets up 117-112 with 17.8 seconds left.
''The game could have gone either way as well as (Lillard) was playing,'' Irving said. ''Anytime someone has a big performance like that, it can go either way when he can really take over the game like he did.''
Irving was also proud of Dinwiddie's performance.
''I'm just trying to stay on him to stay aggressive to be the kind of player he wants to be,'' Irving said of his backcourt mate. ''Tonight was a fresh start for him going into this road trip.''
CJ McCollum struggled for most of the night for Portland, missing 14 of his first 16 shots and finishing with only eight points on 4-of-19 shooting. The normally efficient McCollum has struggled to start the season from the field, shooting 38% overall and just 32%from the 3-point line.
''Obviously you'd like to make shots and I haven't,'' McCollum said. ''I'm not playing the way I want to play offensively, that's quite obvious.'' "
While the win was big for the Nets as they begin their first long road trip, the loss was Portland's fourth straight as they fell to 0-3 at home this season. Lillard has been disappointed with the way last year's Western Conference finalist have finished games so far this season.
''I think we in position to win games and we in position in the third quarter, in the fourth quarter you've got to be present mentally and physically,'' Lillard said. ''You have to do a little bit more than the other team to win games. I think we compete. I think we're together. I think we try to do the right things but that little bit of wanting it more than the other team. And wanting it more doesn't mean playing harder, it means being able to be sharper on one more possession.''
Starting small forward Rodney Hood left the game in the first quarter and did not return with back spasms. That meant first-round pick Nassir Little made his NBA debut. Little got a block and a basket during his first NBA shift, helping Portland cut what had been a 10-point lead down to five. He finished with eight points and three rebounds.
''He had a lot of energy,'' Blazers coach Terry Stotts said of Little's performance. ''I thought he had some momentum plays. I liked his athleticism, his dunks he got the crowd into the game, got our bench into it.''
Nets: Through eight games, the stellar play of Irving hasn't been the only bright spot through a tough 3-5 start. They came into Friday ranked first in the NBA in offensive rebound percentage, which came as an encouraging surprise to head coach Kenny Atkinson.
''I saw that and I was a little surprised,'' Atkinson said. ''We'll see if we can sustain it. But I'm glad because we've also been pretty good at transition defense. If we were 30th in transition defense, I'd be worried. The fact we are balancing those two is a good sign. ''
The Nets faced an added challenge on Friday as they were without backup center DeAndre Jordan. With no real replacement for him on the roster, so the Nets will have to platoon the backup center spot.
''By committee, we can go big, we can go small,'' Atkinson said. ''We'll see a little bit of both.''
Trail Blazers: Adding injury to insult, the Blazers lost another big man in the closing moments of the game when Skal Labissiere suffered a sprained right ankle in the fourth quarter.
After losing forward-center Zach Collins for the next few months due to shoulder surgery last week, an injury to Labissiere is the last thing the Blazers need as centers Jusuf Nurkic (leg) and Pau Gasol (foot) are still out indefinitely recovering from their own injuries.
Stotts did not have an update on Labissiere or Hood after the game.
Nets: At Phoenix on Sunday night.
Trail Blazers: Host Atlanta on Sunday night.
