The play-caller watched his team out-muscle and out-hustle a Czech Republic team who crashed to their second heavy loss in as many days and found it difficult going against a solid Latvia defence.
"Yesterday we played especially bad on defence, but today I am very satisfied with our showing," explained Krumins.
"We allowed only 53 points, we played excellent against their best offensive players, we were maximally mobilised and that's why the score is what it was."
"There is only a small chance we will not qualify for the next round."
Having initially led by double-digits at 12-2 after racing out the blocks, there was little to suggest that Czech Republic would disintegrate. However, they could not compete with the Latvian front-court who out-muscled the Czech team and overwhelmed them by 48-21 on the glass.
It proved to be pivotal in the game and was highlighted by power-forward Kristars Zeidaks weighing in with a classy double-double of 17 points and 12 rebounds while center Martins Meiers harvesting a game high 21 points and 6 rebounds.
The loss was tough to bear on Tomas Satoransky who produced an all action display for the Czech team with 15 points, 6 rebounds, 6 assists and 3 steals.
