In 1950, Hayek left the London School of Economics for the University of Chicago, where he became a professor in the Committee on Social Thought. Hayek's salary was funded not by the university, but by an outside foundation. University of Chicago President Robert Hutchins was in the midst of a war with the U. of Chicago faculty over departmental autonomy and control, and Hayek got caught in the middle of that battle. Hutchins had been attempting to force all departments to adopt the neo-Thomist Great Books program of Mortimer Adler, and the U. of Chicago economists were sick of Hutchins' meddling. As the result the Economics department rejected Hutchins' pressure to hire Hayek, and Hayek became a part of the new Committee on Social Thought.
What was the cause for the feud between Robert Hutchins and faculty?
departmental autonomy and control

In 2003, the season expanded to 16 games. There were also several rule changes in this period. In 2005, players were no longer allowed to run out of bounds. The only way for a player to go out of bounds presently is if he is tackled into or deliberately contacts the side boards. This was also the first year the ArenaBowl was played at a neutral site. In 2007, free substitution was allowed, ending the "iron man" era of one-platoon football. And in 2008, the "jack" linebacker was allowed to go sideboard to sideboard without being penalized for "illegal defense".
What year saw a rules change that had an impact on the role of the "jack" linebacker?
2008
