Your brain is working A-OK I think.
KGB was better for a lot longer. But Keith McKenzie did pretty well for a 7th round flyer from Ball State (not sure if Ball State was even in the MAC back then). Took a while but 2 8-sack seasons for Green Bay and then another for Cleveland.
Would like to do as well in the 7th every year.
