Talented teams do a good job of protecting home court. ISU did it last season (minus UNI), the 99-01 teams did it, and Wayne Morgans NIT Final Four Team only lost 1 home game. I don't think its unrealistic to hope this ISU team can win 8 or 9 conference home games (I went with 8). The other 2 "expectations" I listed are no where near unrealistic.
I don't think it is unrealistic to hope ISU can win 8 or 9 conference home games either. However you said "I think its fair to expect to win all conference home games". Hoping =/= expecting.
I really don't have an issue with your other expectations either. I just think that a undefeated home slate in the Big 12 is a pretty big achievement and to flat out expect it, especially when your team is being picked mid to high mid conference at best, is a little unreasonable.
You can expect what you want, but I think expectations like that are what to lead to our classic CF meltdowns.
