Goff's hands are something he's dealt with forever....
But defenders know trend and an implied weakness can be concentrated on until it is real and greater weakness.
But just as much a problem in Goff's inefficiency or error and production issues are a few more things.
Too much emphasis I on short area throws to same areas to Woods and Kupp making offence 2/3 predictable on where a throw was going.
Injury's to Whitworth and Edwards and very average play by Evans for Edwards.
Inconsit hands by Everett and Reynolds.
A lack consistant use. Of best RB.
Not calling the fade route which Goff throws well.
It's several different things that happen
I ts definitely not ask simple as Goff became unviable or incapable of being a Super Bowl QB.
He played poorly a few games yes.
But it wasn't beyond repair on field.
So maybe the Personalities etc were totally the main issue.
The rest is really overdone trash talk against Goff he is still a very good talent.
