if i was coaching KJ, i'd tell him to look to run often in the first quarter of every game.
opposing defences have to respect his running ability, thus leaving more passing opportunities down field.
the problem with barrett, was he didnt want KJ to run too often, which i feel hurt KJ. it kinda pressured him to second guess himself when the opportunity to run was there ( so many games, u could see he wanted to run, but kinda looked hesitant then made a bad pass instead- altho his injury prolly played a part in some of those).
run run run...defences adjust and second guess your every move, then pass pass pass...defences adjust, then run run run....etc..keep them guessing, keep them confused. throw in some of thos trick plays and u have a very hard team to defend against...not to mention a very entertaining team to watch.
one strength of KJ, is when he decides to hand-off, defences have to be hesitate cuz theres always the threat that he is using the RB as a fake and he has the ball himself.
KJ has all the tools to be a dominant QB in this league...he's not one dimensional like most QB's....he just has to play to his potential every game!
