I don't know, I think maybe it seems like they do, but what teams are you actually referring to? It seems to me to be more coaching and system related - yes, WSU, Texas Tech, Oklahoma State, etc always seem to have a productive quarterback, but (and this is a compliment to the coaching) it isn't as if they are recruiting and/or churning out top talent. Bama has not been consistent. Harbaugh/Michigan still hoping. USC is up there, but still ups and downs. UCLA? Yeah, they had a good one just come through, but before that it was pretty barren for a while. Oregon? Great system. Washington? Gonna be hoping after this year - probably okay though with the coaching and talent. Ohio State? Yes, Urban Meyer always seems to get production in his system. Stanford? Top recruits for years, and even they are left hoping and have gotten inconsistent play outside of Luck.
Anyways, going down the rabbit hole a bit here, and I see your point. I just think that - given that there are only maybe 10 guys on the planet each year who can play that position really well at the highest level - a fan base should not expect to feel reassured at that position year in and year out. Programs should build accordingly to make the quarterback's job easier, through scheme and recruiting. The emphasis on offensive linemen is a positive sign, and Baldwin has a good track record with quarterbacks.
