Foote may be wearing the title, but the board calls the shots. The board put EHH in with a good idea of what they wanted done, and while Foote may not BE Harrison, he still has to keep those guys happy. Word is that Foote is probably an intermediate at that position until a permanent replacement can be found. I don't look for him to make any radical reversals of the course Harrison has set.
I've been of the impression that EHH wasn't calling the shots - he was only parroting what his "handlers" wanted.
I'm not so sure the board had so much to do with what EHH did - they may have hired him, but there was a lot involved with that including intimations of a somewhat hostile takeover. The board may be breathing a quiet sigh of relief.
The question then becomes how much Foote is willing to pass through from Mantle Ridge.
