And look at the run by Jackson at 1:30. Tell me that isn't an exceptional run. He makes a tiny cut to get past one DT, goes into the hole and shrugs off a glancing blow from Brandon Johnson (LB) before powering out of a tackle from the other DT, then takes it to the outside and carries two DBs across the first down marker and out of bounds.
Do you want a video clip of him whiffing on blocks leading to a sack and a pressure? A blindsided sack at that.
Yeah, because blocking isn't something you can learn to get better at...

Yes or no, was that an exception run?
Don't take this the wrong way but the big "
N" by your name isn't exactly reassuring as to your objectivity here. Regardless, the truth is somewhere in the middle here. Jackson may -
may, it's early - have improved his running and vision and is making more decisive cuts, which is wonderful and bodes well for him. We have at this point a
very small sample size to go on, unfortunately.
Even more unfortunate for him, however, is the fact that he damn near got Rodgers (a young QB with no viable backups ATM who already has shown signs of vulnerability to injury) killed on a blindside blitz that he completely misread. Mind you, this was a blitz out of a vanilla, first-week-of-preseason defense.
I don't think it's a mystery which pieces of information - the running plays or the missed blitz pickup - are going to stand out more in the coaching staff's mind at this point. While the one will push to put him into the lineup, the other pushes in the opposite direction very forcefully. He needs to up his game, particularly when the team is quite satisified with the play of the guy starting ahead of him.
