Lol I think its all mechanical. I watch a lot of NBA basketball. The problem often with budding stars is, people stop coaching them because they figure "They've got it all figured out, why waste my breath; he's going to go out there and do what he always does and get us the win". Sadly people jump the gun on Wentz and it looks like he's out of practice on some throws. The thing about Goff and Dak (reluctantly mentioning him) is that they are almost always on the field where as Wentz is always hurt. If you aren't playing, you aren't getting valuable experience. Goff has had the benefit of playing without missing any time. The best ability is availability.
They already paid him, its time to go back and salvage what he was back in 2017. But I'll tell ya, the guy has always had accuracy issues. Just not as bad decision making. I think they just jumped the gun to make the Rams look foolish for drafting Goff who they tried to label a draft bust. And now they are all disappointed that they may be wrong in the long run. Those three (Goff, Dak, Wentz) will always be tied to one another. Its just how it is. And when you get outplayed by the guy who everyone told you were better than; its bound to make a bunch of people turn heads.
