FILE -- This is an Oct. 25, 2009, file photo showing Pittsburgh Steelers kicker Jeff Reed (3) missing the tackle on Minnesota Vikings' Percy Harvin (12), who returned his fourth quarter kickoff 88 yards for a touchdown during an NFL football game in Pittsburgh. Ever wonder why there are so many missed tackles in the NFL? Maybe it's because the players don't practice it much.

Frank Gore runs right up the gut of the Indianapolis defense. Defensive back Jerraud Powers delivers a big body-blow, but Gore just bounces off and keeps on running, one of two broken tackles on the way to a 64-yard San Francisco touchdown.

Baltimore's Ray Rice catches a screen pass and is surrounded by four Cincinnati would-be tacklers _ emphasis on "would-be." Rice's right hand touches the ground, but he keeps running right through the Bengals for a 48-yard score.

With the game on the line, Brandon Marshall outmaneuvers Ken Hamlin, Terence Newman and a few other Cowboys for a winning Denver touchdown in Dallas.

What's the deal? Don't these NFLers practice tackling anymore?

Uh, no. Not really. Go watch a professional football practice. You'll see passers passing, receivers receiving, punters punting and blockers blocking. Yet tackling, one of the game's essential skills and the punctuation mark to nearly every play, usually gets a miss.

"We teach tackling fundamentals," Cowboys coach Wade Phillips said. "But there's no reason to tackle our own guys."

Instead, defensive players are taught not to tackle. They get right up to the ball carrier and hit the brakes, just missing him or giving him a little bump.

Make full contact, and coaches and teammates get upset. Pittsburgh's Hines Ward threw a fit last year when he felt safety Anthony Smith hit receiver Willie Reid during a drill. The Steelers have a tackling dummy named Big Bertha, but that's about as physical as it gets on most training camp days.

Sure, that keeps everybody healthy, but some Sundays can look pretty ragged. Many players get a chance to tackle at full speed only during exhibition games. It shows once the regular season begins.

"It shows a whole bunch," Redskins safeties coach Steve Jackson said. "That's one of the fundamental skills. A lot of people don't tackle now because of the salary cap. You lose a guy because of a tackling drill, you're the dumbest guy on the planet."
