Looking at 40x and weight- shows me LF7 is a FREAK

He's a stud. We've seen it for 3 years.

Plus any RB great will tell you that you're an idiot if you leave your feet to try jumping over people.

Verts give a little more info than just how high someone can jump. You guys know that, right?

For a back, shuttle time is just as important as 40,imo. Did LF skip that?

The bama tards are out in full force saying LF had a disappointing day and ran a mediocre 40. These people live in trailers and probably weigh north of 300.

Because he said no to Bama as a top recruit. They have taken every opportunity to knock him down.

Example:
"LF had horrible games vs us..he suxxor."

Your defense will have 3-5 1st rounders this year and another 3 players taken in round 2 through 4. When your defense scheme is IDEAL to stop the type of offense LSU ran AND you have the talent, wtf did you expect?

At LSU Pro Day, if LF comes in at 230lb and improves his 40 time significantly, then the 240lb time will be his 40 in pads and gear...and that is impressive.

his workouts weren't in "Freak" territory but he did have some good workouts for his size

a "Freak" workout for a 240 lb guy is running in the 4.3s with a 35"+ vertical and like 25+ reps at 225

It doesn't give much more info than being able to jump high.

wrong

which is funny from LSU fans who have been promoting our weight training style for over a decade (there are parallels in the arguments re: measurements v. on-field productive athleticism)

In practically all the world of sport the vertical leap can be and is frequently used as a measuring tool to assess the ability to display power, explosive strength, and the ability to use your strength. Jumping ability is to athletic development what the ability to accelerate from 0-60 is to street-car racing. You can put a bigger engine in a car, but what it can do with the horsepower it has is evaluated in the race. Unless it can "get it up and go" quickly, that extra horsepower is of no use. In much the same way the vertical jump assesses your "get up and go" and how well you can use the horsepower in your own body.

The vertical jump test can also be used to assess your state of recovery prior to a weight-training, speed, or even practice session. If you overtrain your nervous system by performing an excessive volume of heavy weight or high- speed training, the fatigue will manifest itself first in your performance in movements requiring high-speed. You might not notice it much, but this type of fatigue will tend to show itself very quickly as a decrease in performance of the vertical jump. If this happens ideally you'll want to cut back slightly on the volume of your training session(s) to recover. One thing you can do is use your vertical jump as a barometer of how much volume and intensity you should use for a training session.

Where "J" is the speed-strength index, "fmax" is the maximum amount of an available force (strength) of the muscles in a given movement, and "tmax" is the time needed to attain this maximum strength of the muscles.

To maximize J you naturally want a high numerator and a low denominator. From that relationship it can be deduced that the quicker you can produce your maximum strength in any muscle, the more speed strength you can display. This will produce a nice accurate figure that will accurately measure the speed-strength of any particular athlete's movements. The bigger your J, the further you can throw a baseball, discus, or shot, the further you can kick a football or soccer ball, and the more weight you can put overhead. While very precise, this formula's biggest weakness is that most of us do not have the technical means to accurately measure either our muscular force or our time taken to attain it.

Fortunately for you average gym rats there is a more pragmatic way of measuring an athlete's index of-strength. That is done using the standing high jump, aiming only for height, not trying to jump over a bar or anything like that. This is a simple test but an effective one. Anyone can see that the act of jumping upwards as high as possible requires great leg power. You need a great eccentric spring movement, quickly followed by an immediate and speedy concentric muscular contraction of the leg extensors (see video demonstration below.)

This is a good (and easy) way to test potential of a weightlifter since these same qualities must be present in weightlifters when lifting maximum weights. Modern competitive weightlifting is accomplished not so much with the arms, but with the legs, so what works well in the high jump should also work well in the snatch and the clean and the jerk. (That last fact will help you if you end up making bets with people who think that weightlifting is an arm exercise).
