One wonders how many of today’s QB’s would remain pros after taking a shot like Troy took in 1989.
I think that made it easier for him to get concussed throughout his career, especially in the 1993 NFCC.
Brady was great at avoiding punishment, but he rarely faced defenses the caliber of the Giants or Eagles that Troy and Montana faced. The Giants KO’d Montana twice in the playoffs. The Eagles DL broke Troy in 1990. They ended Joe Theismann’s career, and crushed his successor Jay Schroeder’s shoulder, reducing his effectiveness.
The 1970’s and 1980’s were particularly brutal. Staubach and Bradshaw were routinely knocked out of games.
Quarterbacks don’t fear defenses anymore, and that is a huge, huge difference that both Free Agency/Salary Cap and continuous rules changes have made.
