I think Goff is a good system quarterback, when the system breaks down I feel there he has flaws. Fumbles, interceptions, whatever.
I'm a bad amateur musician. But I look at the team this way. Goff is Kenny G or a good session player. Like Bill Bergman (You Belong in the City), Mark Rivera (Billy Joel's guy). They are very good but no Mark Turner or Kenny Garrett who are probably the best currently at improvisation.
If the Lions think they can draft the next Mark Turner, I say go for it. And in today's NFL you're going to need a QB who is able to improvise on occasion.
No knock. I'd just like being prepared in case of emergency. We just saw in the playoffs what happens if your QB goes down. SF had it happen in their most important game of the season.
