Methodologically, Montaillu is still important. Also, Le Roy Ladurie pioneered the history of climate, which Michael McCormick has taken up (he still assigns Ladurie in his graduate seminars).
Why Chester Jordan though? He does not seem to have done anything particularly significant. As for Peter Brown, his most significant work covers the same timespan as Chris Wickham's Framing...., so I think it is a bit arbitrary to include the latter but not the former.
