So is it a dangerous way to play defense that puts not only himself but the other player in physical danger?
No but I wouldn't say its sporting. He literally holds his hand in front of his man's face. He's not playing the ball. That's unsporting, and cheap...
and its freakin brilliant.
What Farve did was he Roger Dorn'd that block. That's it. Whenever Shaq comes down on an opponent's ankle is it a cheap shot? No, because he's a huge freakin guy and its hard to know where his feet are gonna land. Could he try harder? Sure, but we live with it. We don't suspend him for it. Farve whiffed on a block because he didn't extend and opted to roll.
It was a lazy football play, it wasn't even a real chop block. Watch a Broncos game, those things are ruthless. I tore my ACL and MCL and ATT and MCI and CCR once..not while I was playing against the broncos, or anything, but it hurt and it was because of a lazy chop block. If he would've done it right, nobody would've got hurt, and Farve would be getting praised as a "savvy veteran" with an "insatiable love for the game" and a "fan of quotations". Now, by being lazy he looks like a jerk.
BTW..every time during a kickoff return, players collide with the force of a 25 MPH car crash. When tackling a full speed 200 lbs running back from a stationary position, for the defensive player its like a pedestrian getting hit by a car. NFL players have dementia and the laws of physics to worry about, I think Brett Farve gettin lazy on a legit crackback block (as on one that is just clean enough that the announcer goes "wow look at (blocking player's) determination! What a hit!" instead of "Wow, what a scummer!") is pretty far down on things they care about.
