In the grand scheme of Tommy Armstrong's development and career as a Nebraska quarterback, I think we can safely say Brett Farve's influence (whatever that may be) was minimal in comparison to the coaching he received.
I'll admit it's funny to poke fun at Favre's successes and failures throwing some ridiculous passes in his career, but there's one big thing Favre did pretty well that Armstrong didn't - check down.
Yep. Favre has the strong arm and tons of incredible throw only he could make and too many throws he never should have made, but he also did the quickest checkdowns in the NFL. Thousand of Favre's career yards were short checkdowns. If the play wasn't breaking the way he wanted, he had no problem take the 5 yard gain to the wide open RB in the flat. Always wished Tommy would have done the same.
