the 8-10 vs 4-14 is due primarily to 2 things:
1) Seniors in Gip and Nino that have experienced wining and expect to win
2) An actual home court advantage
#2 is the big one.
if the fans continue to support the team, i actually think oscar will be fine. the guy has been dominant at home, even this year, his worst team up against the best opponents the big 12 has ever had. in three years, oscar is 8-1, 8-1 and 7-2 at home. that's 23-4 at home. that's incredible. when you're that good at home, you can afford to be way below average on the road (3-6 yearly) and still make the ncaa tourney regularly.
i would strongly suggest oscar stop scheduling hard non-con games away from home in the future. there will be plenty of opportunities to get quality wins in league play under the current scheduling format, and with the league's quality being where it is.
