The Gonzaga big men look for another strong collective effort while trying to the lead the ninth-ranked Bulldogs to a ninth consecutive victory over visiting Idaho on Tuesday night.The 6-foot-10 Daye and 6-11 Heytvelt each had 15 points and combined for seven blocks in Gonzaga's 83-52 season-opening rout of Montana State-Billings on Saturday.The Bulldogs hope that duo's combined effort will be a regular occurrence for a team that includes reigning West Coast Conference player of the year Jeremy Pargo, who had 10 assists on Saturday.Daye, who averaged 10.5 points and 4.7 rebounds last season as freshman, grabbed 12 boards in 25 minutes and showed little effects from a knee ligament that was partially torn over the summer.Heytvelt, who posts career averages of 11.0 points and 5.5 rebounds, pulled down eight boards to open the senior season of a career marred by nagging foot injuries and a suspension for drug possession that put a premature end to his sophomore season."When you see them every day, you don't always notice it," Gonzaga coach Mark Few said. "Austin looked strong and he did some of the things we need him to do inside. Josh is the healthiest he's been since he was a sophomore. It's good to see him come back strong."Daye, who had two double-doubles in 33 games last season, added 16 pounds to his upper body during two months while resting his knee."He was really making a lot of progress before he got hurt," said Few, whose team shot 56.7 percent from the floor in the second half against Billings after leading by just five points at halftime. "It's too bad he lost that time."While Heytvelt missed Gonzaga's 80-43 victory over Idaho last November while recovering from foot surgery, he had 16 points and 11 rebounds in the Bulldogs 25-point win over the Vandals in 2006.Daye recorded 18 points and six blocks as the Bulldogs shot 56.0 percent and held the Vandals to 13 second-half points last season.Gonzaga has dominated Idaho since losing 71-64 to the Vandals on the road Jan. 5, 1998.Idaho (1-1) will face its second straight ranked opponent after falling 100-62 at then-No. 6 Michigan State on Sunday. Washington State transfer Mac Hopson had 13 points and five assists for the Vandals, who committed 22 turnovers and allowed the Spartans to shoot 59.6 percent from the field."We did some good things, however those good things only came in spurts," said Idaho coach Don Verlin, whose team opened with a 91-69 victory over Evergreen State on Friday. "We are all such competitors and we didn't feel we played as well as we should have."Trevor Morris, who's averaging 10.0 points in two games, had 10 and was one of two Idaho players in double figures against Gonzaga last season.Hopson has scored 32 points and recorded nine assists through two games for Idaho, which is 0-16 versus Top 25 teams since the beginning of the 1999-2000 season.
