Everything is Kalani's fault because he is the Head Coach. Everything fall's on his shoulders.
IMHO... The offensive plays made no sense, the offensive players didn't know what they were doing and player moral sucked. That is the fault of the position coaches not Kalani. Everybody who needed to get fired got fired. Players who needed to leave the program have left.
As the head man, Kalani takes the heat and fan hate even if it's not deserved. It will be interesting to see if people will give him credit if the team starts showing success.
If you talk to players from the past who have been coached by Kalani you'll see how respected he is. (Trevor Reilly was asked to rank the top coaches he's worked with on the radio this past week... Belichick was #1, Kalani was #2)
