Well Frost, Crouch and Lord played in a system designed for passing efficiency: far fewer attempts, element of surprise and safe routes that rarely involved multiple options or checkdowns.
Backed by outstanding offensive lines that gave them lots of time, and play action that got defenses to bite because we ran so often.
So my memories are of those QBs standing tall in the pocket, spotting wide open receivers, and hitting them roughly 50% of the time.
There was one televised game Frost was playing and iirc Joe Theisman or another former NFL QB was doing color, and he telestrated several plays showing Frost's poor mechanics, often holding the ball a split second too long so that the tip was pointing down and the pass went to the receivers feet. Theisman showed plays where the receivers managed to catch the ball, but Frost's failure to simply lead his receivers left lots of yards and potential TDs on the field.
When Crouch was given the chance to play in one of the Senior Bowls as the reigning Heisman Trophy Winner, I think he threw three interceptions.
They threw well enough for option football, but they didn't throw as well or with the degree of difficulty as Tommy Armstrong.
that seems to be a criticism of the past 2-3 qb's as well.
And one for about 90% of QBs.
The reason why NU had guys running open where "leading them properly" would have resulted in more yards and tds is that you had a legit running threat QB which pulls a guy or of coverage.
Take away that running threat and replace him with a "good thrower" and those receivers suddenly aren't running as loose.
That's why I wouldn't trade a mobile QB for a guy who can efficiently throw the ball 30+ times a game.
Properly leading an open receiver is Passing 101. Not sure your rationale makes much sense here. A bit with linebackers maybe. Not with DBs.
Frost wasn't a good passer. That's not too controversial.
Good passing quarterbacks don't have to be immobile. They don't have to perform like running backs, either.
Nebraska has been enamored with dual threat quarterbacks for years now, but running is priority and the passing tends to suffer because these guys never throw as pretty as they do in those high school films.
And if you look across the college and NFL landscape, everyone is enamored of dual threat quarterbacks but it seems more often than not they bring a liability with them. As exciting as dual threats are, the competent passer and game manager is usually the QB left standing.
I know you think pro-style passing QBs are a rare talent, but I don't think they're any less common than a good dual threat QB. I'll take either one, myself.
