There really seems to be two points in this argument:
Group A thinks Tarvaris Jackson is the perfect BACK UP QB, despite his pedestrian stats he has familiarity within Bevell's system (he has been in Bevell's system in all but 1 season), T-Jack garnered mad respect of his Seahawks teammates during his 2011 season as the Seahawks starting QB , so much so, that the Seahawks had to trade him in order to move the chain of command to either Wilson or Flynn. While Jackson has pedestrian stats, he is still better than Quinn.
Group C thinks Tarvaris Jackson isn't the answer and never will be. They have argued points against him as if he will become the starting QB. Stating that he has slow drop back and an even slower read. Argued against Quinn is that Quinn has never been on good teams and still has a considerable amount of upside. (Which is almost fruitless because T-Jack was drafted in 2006, Quinn in 2007). T Jack couldn’t also survive the Buffalo Bills. So he’s worthless. Except for the facts that T-Jackson had to endure 3 changes of scenery in 3 years, 1) Vikings to the Seahawks in a lock-out shortened year 2) Seahawks to Bills in a trade in which he had to learn a new system for the first time in his career 3) Coaching change, FO change, meant another new system on the only team that spent a 1st round pick on a QB.
Simply to say Jackson isn’t worthwhile or worthless because he didn’t do jack squat with the Bills is a very cheap and ill formed statement.
However, the camp in Group A and the camp in Group C need to conform to the logical reason to those of Group B:
1) Tarvaris Jackson, although signed, isn’t going to be handed the back-up job, he’s going to have to compete for it with Quinn and Johnson
2) That fans can think and say whatever they want, but it’s the Seahawks that have the final decision as to who will make this team, they’ll pick the best guy they feel is best fit to backup Russell Wilson.
3) Whether that guy is Jackson, Quinn, or even Johnson… the best way to find out who will be that guy behind Wilson is competition…give the QB who probably thinks he’s in comfortable space a reason to watch his back, make the QB who is fighting for a chance feel like he has an even slimmer chance, and give another opportunity to a QB that deserves another opportunity to be part of this team but guarantee him nothing…. One of these guys will come out on top and likely better than they were going in.
It is not about “Who your favorite?” or “Who deserves it?” or “Who has the most upside?”… It’s about constructing the best 53 players out of 90 or so players and winning some damn football games to hoist a Lombardi.
Speculative: All the air missing from Tom Brady's deflated balls now inflates KAM CHANCELLOR's growing ego.
