Man have times changed.
Here is a blurb from CBS Sports:
Rams (4-0) at Seahawks (2-2)
Opening line: Rams -7.5
This is one of the most interesting point spreads of the week and that's mainly because the Seahawks are almost never a huge underdog at home. Since Pete Carroll took over as coach in 2010, the Seahawks have been a home underdog of seven or more points a total of only two times, going 1-1 both straight-up and ATS. If you ever want to take an underdog, taking the Seahawks at home always seems to be a smart bet. Since 2011, the Seahawks are 9-3 ATS as a home underdog and 7-5 straight-up. That being said, if any team can cover a spread like this in Seattle, it's the Rams. During Sean McVay's first season as head coach, the Rams handed the Seahawks their worst loss in CenturyLink Field history when they beat Seattle 42-7.
