If you spent 3 minutes to learn about the two individuals you are comparing, you wouldn't have written that. There is a reason Mike Vrabel (who met him as an established veteran meeting a rookie in 2009) hired McKenzie as his LB coach two years ago.
The only thing those two had in common was that they were football players drafted by the Patriots.
Just to shine some light into exactly how bad your uninformed snarky comparison of Tyrone McKenzie to Chad Jackson was:
Tyrone McKenzie - Wikipedia
"....Before the 2007 season, McKenzie transferred to the
University of South Florida, receiving a hardship waiver from the NCAA allowing him to play immediately. McKenzie had transferred to be closer to his widowed mother who was injured in a car accident and lost her business; McKenzie worked the overnight shift at a
Hampton Inn in order to support her.
