You're right his release is very good ,he can get the ball there quickly and accurately up to 35-40 yards .
I do see he has some challenges with exactly how much air or power to put on some of the longer throws some what randomly.
What it seems on some throws is a measured toss rather than a full distance throw and I think that throw to the faster guys on the roster is the most difficult hook-up period.
You are kind of caught between putting the ball there earlier and it may be a bit high and soft ,,very,defencible or powering it on a line and holding it as long as possible and being hit by rusher or making a throw that is inaccurate to the route and pretty much just an overthrow or bad throw.
Goff it seems to me is trying to capture that middle ground between touch and strength and most f time he's in the zone to make the completion happen.
Can he throw the ball further on some of these plays like the one to Sammy or the one to Josh Reynolds ,,,??
Yes and I'm sure he will going forward as he stores more muscle memory with all the different Receivers going deep.
For now he's pretty darn ok and hits passes downfield as innately as any of the other QBs out there with less than 5 yrs years exp.
He's got the arm and he's using it as appropriate to the best % effect.
I'm fine with that.
