There is no Defensive "Book" on Stafford as a member of the Los Angeles Rams.
There is probably some trends over his career as a Detroit Lion but that was a different organization with several head coaches running the show with an unstable front office.
I won't even try to break down all of the intangibles involved that would give some solid examples of the defensive book on him.
For myself, I need to see some of these negative trends he displayed in Detroit translate to his play in Los Angeles before I guess the defensive book on Stafford.
On paper he's the best QB the Rams are starting under center since Kurt Warner.
We will learn the defensive book on Stafford as the 2021 season unfolds.
I have a hard time crossing over his negative play during his Detroit years until I start seeing some of the same patterns under McVay's watch.
I'm sure there are a few pages from the defensive book on Stafford with 12 seasons in Detroit to observe.
My opinion is the Detroit book closed the day he was traded to the Rams.
There is a new author (McVay) and a new cast of characters and proven commodities that Stafford has to work with.
As Aaron Rodgers was recently quoted saying,
"it's a beautiful mystery."
