The veteran understands his job.
"My job is to come in when (Robinson) is tired and be the relief. I feel like when I come in the game it's like another starter coming in the game. We won't have to worry about any type of fall off or lack of play from second teamers."
On Monday, October 7th, McKenzie will line up against his former team, the Green Bay Packers in primetime. The defensive end will have to line up against old teammates but he insists it does not bother him.
"That's all in the past, the last time I played with Green Bay in 1999, this is 2002. I am a Chicago Bear now."
McKenzie's objective is to now chase down elusive NFC North quarterbacks such as Brett Favre, Daunte Culpepper, and unknown rookie Joey Harrington. The Bears have had a weak pass rush in years past, but McKenzie should bolster the team's pass rush this season along with rookie Alex Brown.
