I'd assume for assistants he'd want one Xs and Os guy, preferably defense minded, and 2 recruiters. I'd assume he'd try to get a development guy in a non-assistant position
Hoiberg is a relationships guy. I'd start with the former assistants under Hoiberg
Matt Abdelmassih 2010-15 – Currently an assistant coach at St Johns, his alma mater. Met Hoiberg when they both worked for the Timberwolves.
T.J. Otzelberger 2010-13 – Currently the head coach of UNLV Was a carry over from previous Iowa St coach Greg McDermott's staff
Bobby Lutz - 2010-2011 - Currently unemployed. Was coming off 12 years as Charlotte's coach before moving to Mark Gottfried's staff at NC State
Cornell Mann 2011-15 – Currently an assistant at Missouri. Was recommended as a coach to Hoiberg by former Iowa St assistant Ric Wesley
Doc Sadler 2013-14 – Currently the Head Coach at Southern Mississippi
Charlie Henry 2014-15 – Currently the head coach of the Windy City Bulls, the Bulls G League team. Started as a Director of Player Personnel and was promoted to assistant under Hoiberg. Hoiberg took him along to Chicago as an assistant.
Nate Loenser - was a grad assistant under Fred and worked previously in some capacity under Larry Eustacy and Tim Floyd. Nice article on him here, Was the coach of the Windy City Bulls but swapped jobs with Henry and now is an assistant
Shawn Respert - Currently an assistant with the Bulls, was part of Hoiberg's staff there. Former Michigan St guard.
Someone brought up Tim Floyd in another thread as he's connected with Hoiberg. Think he's currently unemployed and certainly knows how to coach.
