"He walked in and talked to me the other day and he's as square as the door frame," Dorsey said. "He's just a very big guy, he's very strong at the point (of attack)."

The Chiefs will remain in a 3-4 alignment under new defensive coordinator Bob Sutton, but will likely employ more aggressive blitz packages similar to the scheme Sutton ran with the Jets. In third-down situations, Sutton could switch to a 4-3 on occasion to give Jackson more opportunities to rush the passer.

"I can't wait to see what the coaches are doing to kick him in on third down to see if he can push the pocket," Dorsey said
