Taken out of Notre Dame by the Baltimore Ravens 86th overall in 2008, the 28-year-old Zbikowski was clipped by the Chicago Bears on August 25.
Now employed by three organizations, the two-time member of the AP All-American third-team has only amassed 126 tackles, two sacks and three interceptions over 64 games.
Hence, it has become readily evident the 5-foot-11, 200 pound Zbikowski is nothing more than a middling ballplayer.
However, the tough Irishman is an extremely promising prizefighter.
Since debuting as a professional pugilist in June 2006, Zbikowski (4-0, 3 KOs) has shown solid power and deft footwork in the ring.
Compiling an amateur record of 75-15 since becoming a boxer at the age of 10, Zbikowski trained with Hall of Famer Emanuel Steward during the 2011 NFL lockout.
Rather than lagging on the gridiron, Tom Zbikowski should quit football and become a star light heavyweight in the squared circle.
