Wrong, tough guy.
Football as we know it will be gone, 5 years, maybe 8. The lawyers will win. Too many concussions and other injuries.
They will start with "touch football" rules as it pertains to the QB.
Not enough.
They will have to change so many rules to prevent lawsuits, equipment, etcetera. Humans have exceeded the point of no return weight-speed-strength-power for football.
I personally think weight limits are the only answer, say 260 for lineman, 215 or so, everybody else.
Weigh-ins every Thursday, you get a 3 lb mulligan 2x a season. Something like that. Or you sit.
