See this is where I don't get the whole "value" thing when it comes to a QB. Surely either a QB is a legit franchise QB or he isn't. If he is, it's a success at absolutely any pick. If he isn't, it's a waste of any pick. I don't see QB like other positions where you can get away with having a mediocre player here and there in among a team of mostly better players. The QB is everything. Whenever you get deep into the playoffs, it's always teams with franchise QBs who are competitive on a consistent basis.
So to me, QB is more of a binary thing than other positions. He's either the guy or he isn't. It's fine to have a guard or a linebacker who you spend a 5th round pick on and he's just a guy. The value there is fine, and you probably have better players around him. He's just a cog in the machine. I see no such value in a later round QB because all it means is you still need a better QB.
I just can't care about "value" at the QB position at all. That's why if he doesn't take a swing on Watson/Kizer/Trubisky, I'd almost just as soon he not bother until next year and go for it then. Mid-to-late round developmental prospects are just a waste of a pick imo, when you could have had another positional player actually contributing or even starting.
