No doubt about it Coach.....The game is being "watered down" especially in the NFL, which usually filters-down to the college ranks & below. (zealous QB protection), (receivers and running backs receiving interference/roughness calls), Remember when the kick-offs were from the 40 yard line and the kickers began to boot the ball in the stands; They had to move the kick off yard-line back to allow (encourage) more kick-off returns. The 104 yard kick-off return was always one of the high lights of the game (maybe the season).
Todays equipment plays a leading role, resulting in more injuries in all aspects of the game, not just kick-off/returns; (The high-tech helmets), the disappearance of the knee pads, and the "watered-down" (lighter) hip and shoulder pads which, today, are about the size and weight of a woman's bra and girdle, high-tech uniforms (jersey's and pants) all of which allows for more speed which is the real (injury) culprit today. Each NFL prospect and all college recruits today are clocked for seed.....
What are we going to do next, rule-out or penalize excess speed.........If speed was curbed it would cut down on the injuries (considerably).
We can't have it (both ways) in the game of football (a contact sport). Quoting John Madden, "Football is a game played by Warriors"....That is why
football is the most popular (idolized) game/sport in America today, attested by the fans who are willing to pay the price of admission to watch the game........as we know [it].
