It has the potential to be a fascinating offseason, especially if Goff gets traded... which I find highly unlikely. I've never been a huge Goff fan. I like him and have defended him but he has limitations and I agree he needs ideal conditions to be great, as do most QB's. I would love to see him traded if they can re-work his contract but I think that is unlikely. And I have a problem trading away a good QB which I think Goff is.
Minshew. I don't know a lot about him. He is mobile, can buy time in the pocket and extend plays. He has a good enough arm. At 6'1" he's perhaps a bit on the short side. Jay Gruden said he can be a great QB. I've only seen highlights... he would definitely add and element to the offense but so would Wolford. Not knowing any better, I am all for it! lol
I like all of the moves you mentioned. I wish the salary cap was more friendly for your own drafted players. I like John Johnson and would hate to see him go but ...
