Eh? I never said anything about greater interference after Fergie?
What happened after Fergie? As far as we know, they (the Glazers) left Woodward in charge.
To what extent did he interfere with football operations? Hard to say, but he (his role, the entire era) can be dismissed as representing what I said above: the structure was entirely fecked up.
Woodward (whatever the feck he actually did or did not) clearly isn't an example of the Glazers being hands-on, though, quite to the contrary.
Woodward either replaced Gill...or he actually replaced Fergie too (as the chief decision maker on the football side), depending on who you believe. But he was nevertheless someone the Glazers trusted to take care of things. They, themselves, remained hands-off as far as we know.
