I dont think so.
Before last year it was just for the superfan option.
I even googled it and found these posts:
from 2007 --
"The free preview is for SuperFan, the $99 option for Sunday Ticket subscribers (which many of AVS subs get for free after calling customer service anyway).
Non-Sunday Ticket subs are not getting any NFL coverage other than their local FOX/CBS stations."
from 2009:
"Yes, NFL Sunday Ticket will have a free preview this year on the first Sunday. This is the first time this has happened.
In years past, Super Fan was in free preview but this year the whole ball of wax, in HD as well."
