I am skeptical about Jackson's success moving forward. I absolutely love what Roman has done to maximize the talent on that team's offense. I think Jackson is a great fit for that scheme and, I agree, he's better that Kap or TT. He runs better than either of them and he throws with more anticipation.
I'm a Georgia Tech alumni and had an uncle live with me who was a Naval Academy grad. Suffice it to say, we saw a ton of triple option, run-heavy, misdirection, RPO plays to last a lifetime. These types of offenses completely confound teams that haven't played against them much and Baltimore's team last year was the epitome of this. Team's were completely lost in gap coverage and receiver coverage throughout most of the season. However, over the course of time, team's like this get "figured out" by teams with time to prepare. It's one of the main reasons GA Tech and Navy lost so many bowl games. Teams had a couple of weeks to watch tape and get ready without having to face anyone else. That will start happening in the NFL this year to the Ravens.
We saw this start to change beginning with the SF and Bills' games. Disciplined defenses were able to hold them down and limit Jackson's effectiveness by making him throw outside the numbers, where he was particularly poor. Tennessee put down the hammer.
If Jackson can improve his skill-set from the pocket, he will continue to excel. If he can't, he becomes a really good Tyrod Taylor and will continue to win games provided his team has an awesome defense. Anybody who scored 25 points against the Ravens last year beat them. John Brown runs a better route and catches that TD late, the Bills take that one to overtime with 24 points.
