Why do ';system quarterbacks'; such as Colt Brennan, Case Keenum ect. carry such a low value in the NFL draft?

I know that the offense these teams (Houston, Texas Tech, Hawaii, ect.) inflate the quarterback's numbers but if they are throwing it so much more than quarter backs coming from a ';pro'; style offense like Stafford, they have much more experience throwing the ball and making reads. Why is their draft value always so low?Why do ';system quarterbacks'; such as Colt Brennan, Case Keenum ect. carry such a low value in the NFL draft?
Because ';system quarterbacks'; usually run a gimmicky style that works in college due to a difference in talent. There are 119 or so FBS (formerly Division 1A) schools. There are 32 professional teams. Speed, being able to read a play, and other things are much more even in the NFL. The secondarys are too good and the action too fast. It's also why an option run offense doesn't work in the NFL but still does in college. You could not run Navy or Georgia Tech's triple option in the pros.Why do ';system quarterbacks'; such as Colt Brennan, Case Keenum ect. carry such a low value in the NFL draft?
The so called experts think that a quarterback who takes a shotgun snap, are unable to take a snap under center. That is the dumbest thing I have ever heard. You still nead to read the defense if your in the shotgun. And NFL QBS are in the Shotgun alot anyways in passing downs. Graham harrell should be starting for some team for example the bucs, panthers, rams, redskins, titans, dolphins, seattle, raiders, starting qbs are terrible and they could all use graham. The NFL loves guys with big arms aka '; The Jamarcus Russells of the world who cant hit a reciever 10 yards down field but thats ok cause he can throw the ball 70 yards JUST NOT ACCURATELY! Honestly it makes me sick to watch Graham Harell go undrafted and Brennan go in the 6th round when they can easily start for several NFL teams. Hey when is Jim Zorn gonna give Brennan a shot How many games are you going to put up 9 points with cambell before you try Brennan for 1 game. Brennan would not have lost to the lions I can tell you that!
It's because that in the NFL, the game is so much different. The NFL teams want QBs that have been in an offense in which they run a playbook


similar to what they will see in the NFL. Plays that they will have to be making in the NFL.


Taking the ball from shot gun every play does show that you may not be able


to make a transition to under center because you have to work on the footwork


more, and so you will have to worry about taking the right steps,


reading the defense on the fly, and you no longer have a headstart on D-linemen.


And also, most teams will run plenty of screens as was pointed out in a previous reply.


Or they will at least have a back to stay in and block,


then if protection breaks down, they are taught to be ready for a dump off.
The NFL offense is so complex that having learned four years of a similar system in college gives you a head start on other guys. If two guys have similar physical traits and can make similar throws, the guy from a pro style will get the nod everytime. Look at all the top quarterbacks in the pros right now and youll see that the college pro style quarterback takes the cake. Brady, Manning, Roethlisberger, Rivers, Palmer, Hasselbeck, Brees, Ryan....look at the big name spread QBs to come out of college: V Young, Kellen Clemons, Alex Smith, Rex Grossman, Joey Harrington, etc. All the latest high round spread QB busts
because their stats are padded with about 6000 screens a game.. see in those pass happy Offenses they don't run the ball but use WR screens like a running game.. so.. they throw for 40TD's but 23 of those were on passes of 10 yards or less where a guy got lose in space.. really just doesn't translate well to the NFL style of offense





to respond to the post below about the skins and Brennan.. it ain't Campbell that's the issue.. the issue is whoever the QB is doesn't stand a chance to succeed in Washington right now.. their top WR played QB for Indiana in college.. the offensive play calling is horrible..
They typically don't have the arm strength or accuracy to make any throws more than 10-15 yards.





To the guy above. The shotgun is pretty much a give away that you are going to pass the ball. Usually the defense has to decide run or pass then adjust from there. Now that you eliminated the run before the play even starts you are just giving them a head start.





Graham Harrell is a great example of a guy with no physical abilities. He got a tryout from the Browns and didn't even get a contract offer.
It has nothing to do with being a system QB, and everything to do with the ability to make NFL throws. The game is much faster, so they need a stronger arm. A lot of ';system'; QBs lack the arm strength to throw deep outs, and therefor NFL coaches shy away from them. As a matter of fact, most college QBs lack that ability, and that's why they never make it at the next level.
Because they aren't as good at ';managing a game.'; Your QB has to be like an OC on the field.
