I think Josh was forcing it to Diggs for a couple years at least to keep the yapping in control.
I think when Brady came in there was a few games where Josh was throwing to who ever was open, running game working ...stick with it.The offense blossomed. Shakir, Cook, Kincaid etc... Diggs became cryptic again..
Not comparing, but Brady won with basically scrubs at WR & RB. They just balled to whoever or what ever was working.
I'm hoping this is the break through that the Bills achieve finally. Don't force it, spread it around. Josh is the greatest player we have, let him do his thing and he will make great moments for all of the offensive skill players.
You don't need a #1 receiver when you have a #1 QB.
