Grizzly hoops faltered out of the gate Sunday and San Francisco jumped all over the inadequacy bursting to a quick 10 point lead never looking back to send Montana to a 76-57 road loss.
The Grizzlies visit the Bay Area for a pair as part of a seven-day road trip.
Martin Breunig continued to have foul problems, playing just 24 minutes against the Dons, but again led the Griz in scoring with 14 points to go along with eight rebounds after a double-double at home last week against Carroll.
Jermaine Edmonds Jr. is starting to show signs that he may be the team's best pop-up and clean shooter and added a career-high 13 including three of nine from outside the arc.
But Montana (2-3) was badly outpaced in the paint (40-18) and shot 21 less throws and while improved play after the break gave them a slight chance, USF pulled away for their seventh straight victory over Montana.
But Wednesday they face even a tougher challenge as they venture into Berkeley to challenge California of the Pac-12 who are unbeaten in three home games and stand 5-1.
They defeated then No. 25 Syracuse 73-59 before losing to Texas in a tournament championship 71-55 and Sunday won at Fresno State by seven.
Sophomore guard Jordan Mathews paces Cal at almost 17 an outing and connects on just south of half of his third-point attempts.
6-foot 5 Tyrone Wallace is right at his heels and drops about five dimes an outing and leads the Bears in rebounding while shooting some 46 percent from the field.
Sophomore Jabari Bird adds about 13 an outing and 6-foot 10 David Kravish also contributes double figure scoring while grabbing about five boards a contest.
Cal is a high scoring lot (77 per outing) and allows opponents just some 35 percent and less than 60 points from the field.
The Bears only turn it over less than double figures while outrebounding opponents by better than six a contest.
California's bench scoring in the early season looks suspect but nine players contribute double-figure court time with the double-scoring quartet playing an average of some 28 minutes an outing.
Tipoff at 8p.m. MT Wednesday
