If Lynch turned out to be the franchise QB, and that doesn't mean Brady or Montana, or even Romo. The how would he not be worth the 4?
I dont think "value" should be looked at as a "what if" perapective. His overall abilities, intangibles, and potential has been rated as being around the 15th to 25th best player, on average.
If you look at "value" in a mathematical sense in terms of drafting, the higher you draft the better player you can get. However, if you don't do that then you have lost value at the specific moment in time and as it relates to the opportunity to maximize that value.
Suppose you could trade down 3 spots for a 2nd round pick and then get Lynch.
Or suppose somebody else wishes to trade up with the Cowboys for Lynch and gives their #1 and their #2 and perhaps more.
Now suppose one of thos picks turn out to be Hackenberg plus a DE that turns out to be a real contributor.
So then, who is to say that it isn't Hackenberg rather than Lynch that becomes the true franchise quarterback?
So, Im not really predicting who will be the future star, if either. Im just saying they should maximize their value because this is the value given to the 4th worst team during the previous season.
