It's amazing to me...The biggest, strongest, fastest football

players in the history of the game and they still can't tackle.

I'm not talking about a great offensive move to avoid being

tackled, just what appears to be a fundamental football tackle.

Wassup w' dat?

I think you answered your own question.  The defenders are going up against the "biggest, strongest, fastest football players in the history of the game."  Some of the offensive players today are just downright, well, offensive in the hits they deliver to the defenders.

Players are too caught up in the "big hit" and neglect to wrap up in favor of leading with their shoulders/helmet in an attempt to knock the other guy out instead of taking him down.

Or... It could be that, while these players do appear superhuman in ability, when it comes down to it they're still just... human. They get tired, confused, tricked and lose concentration and focus like the rest of us.

I know that Adrian Peterson ran over #22 today like a Mack truck.

    AP is a beast.

About basics.   Today, Whitten caught first down pass with less than 5min to go and evades contact to go out of bounds which stops the clock.

    He could have slid down and evaded contact, had first down without stopping the clock.

     Not what you expect from pro bowl veteran.

Just basics.

Too often the defender is so focused on stripping the ball that he misses the tackle altogether.

   I see a lot of that.  I call it "fairy tackling".  There's just no attempt made to trap the guy and hobble him so that he can't gain yardage.  If they did that, it allowed others to move in to stop his progress and take him down.  In addition to doing that, I'd think that most of the serious injuries caused by a hit in the worst location would be avoided.  Having a big guy falling on you after being slowed down to a crawl beats having to send him to the hospital with his leg practically broken in two (not to mention you with your ringing head).

RW,

While you make a great point, you forgot one important aspect. 

That is the "Victory Dance" that the defensive player must put on full display when he finally does something he deems worthy.  Barely does it even matter that his team may be down by three or more touchdowns at the time.

Nothing could be sadder than watching some buffoon revel in individual glory, while playing a team sport.

It's not the size of the dog in the fight, it's the size of the fight in the dog.

D. Hall and the rest of the Redskins secondary are the biggest victims of the FTS. Aka the Fairy Tackling Syndrome.

some tackle to win a game.

some tackle in ways to not get hurt.
