I had to post that, he's short and his arm is okay, but that's what I don't want. If a QB is going to replace Goff, I want somebody, bigger, stronger and faster like Jamie Newman for example, but Minshew is not that and IMO is a very good backup. I've seen countless trades involving him and I believe Minshew is a good enough QB to make you lose...No thanks.
As to the rest of your plan, traded are fine, but you must have a partner that will make the deal, you did not post what team would make that deal for Goff and as to the draft choices, if would be nice to know who you like with all those draft choices.
