The Chiefs selected Tyson Jackson with the third overall pick in the NFL Draft two years ago and they are still waiting for the defensive end to make an impact. Jackson has started just 17 of Kansas City's 33 games since and he has just one sack to his credit. "Everyone in our organization," general manager Scott Pioli said, "is pretty confident still that Tyson is going to be a good player." There is little doubt that next season will be critical for Jackson. NFL people suggest that much of any player's first two seasons are spent adjusting to the league's speed and demands. It's the third season that reveals something closer to reality.
