It's not crap. It's science. If you're not smart enough to understand the basics of it, that's on you...

You are combining physics and biology.

Yeah, it's called Bio-mechanics and it's a whole field of study....

You are introducing a new theory that the whip wears out a QBs arm.

No, I'm saying a QB with a shorter arm has to apply more muscular force to a throw, every throw, for their entire career to maintain the same velocity. This could lead to more muscle fatigue for that athlete over their career. As an athlete ages (and SB is already 25) and recovery times increase this makes it harder for this athlete to perform at the same level over the course of their career.

Long story short pun (intended), short armed QB's are at a disadvantage to long arm Qb's. And it's science...

I'm speaking in a theoretical fashion. If your UGA education can't see that, I'm sorry you wasted you money....

Here you go Einstein.....

Putting The Physics Back Into Football: Short Qbs

According to ESPN Sport Science, in 2009, quarterbacks 6'4" and over averaged 5% more completed passes and averaged three more touchdown passes than quarterbacks 6'1" and under. But the reason may not be directly linked to their height, but rather the length of their arms; and taller guys tend to have longer arms.

When a quarterback throws a pass, they generate force through their legs and trunk and send it though the lever that is their arm. The arm will then begin to turn inside the shoulder socket at an angular velocity dependent on the amount of force they generated from the rest of their body. The ball's distance from the axis of rotation, which in this case is the shoulder joint, times this angular velocity is what determines the speed of the ball when it is released. This is similar to of a ball at the end of a string, the longer the string, the faster it can be spun.

Here we have two of the exact same quarterback, that generate the same amount of force from the ground and use the exact same throwing mechanics, the only difference being that one is taller and has a longer arm than the other. Since both generate the same amount of force, both will have the exact same angular velocity and therefore, the ball will be released by each quarterback at the same time. However, the arc which represents the ball path, is much longer for the long armed quarterback, and therefore travels a larger distance in the same amount of time, resulting in greater ball speed.

The length of the quarterbacks arm also aids in releasing the ball higher off the ground which is key to making short and quick passes.

All quarterbacks have different mechanics and release points. Players like Tom Brady release the ball high away from the top of their heads, while others like Philip Rivers release the ball only a couple inches above their head. This is all fine as long as they're able to throw the ball in a straight line above the heads of the linemen and make those quick bullet passes. However, this is a situation in which shorter quarterbacks may have an issue.


Taller quarterbacks are able to throw the ball in a straight path while shorter ones with a release point below the heads of their linemen have to arc the ball over the heads of their linemen. This becomes a very big issue when it comes to short passes because it limits the amount of speed the quarterback can put on the ball: too much and the pass will go too far. This causes passes to hang in the air longer and may require a quarterback to throw the ball much earlier. This impractical anticipation requirement often results in bad timing which is crucial in the short-intermediate passing game. So the impairment that short quarterbacks have is not about how far their heads are from the ground, but rather how far their hands are.

The receiver transfer from State got arrested the first week he was there. I don't bother with names anymore due to the portal but seems like Williams or something like that.

ETA - looked it up Rara Thomas.

He is also 38 years old and still can't handle his alcohol

I think those charges have already been dropped.

Ummmm. You said his arm would wear down faster.

Quit being obtuse. You know what I meant. No matter how you UGA fans want to spin it, a short armed QB is at a PHYSICAL disadvantage to one with longer arms. It doesn't mean they can't make it in the NFL (and I never said he wouldn't). It also doesn't mean there aren't other factors that also contribute for him in a positive way. But for the one specific thing I talked about, arm length, and how it relates to throwing motion, muscle fatigue and recovery (both short and long term), SB is at a physical disadvantage to someone with longer arms. The longer arm QB can make higher velocity throws with less muscular input that someone with shorter arms. Doesn't mean a short Arm QB can't make the throws, it jut means it takes more muscular effort. Over time that workload adds up. It's not very complicated. As I said, it's physics and unless you live in an alternate universe (like many UGA fans, including yourself, do) you can't change it because you can't change the laws of physics.

Genetics is the largest determining factor in an arm wearing down

Well at least you're right about this. Guess where SB got his T-rex arms? His mom and dad.....

The ball ain't heavy.

The mass of the ball doesn't matter (Well it does matter, but it doesn't matter as much as velocity). Force = Mass * velocity squared. It not the mass of the ball, it the velocity of the arm movement and the muscle contractions needed to generate that velocity that are at issue.

And I'm not arguing anything. I'm just responding to you not understanding high school level science.

I just don’t think a “5-10 year backup” will throw enough for this matter in any noticeable or relevant way, which is why it’s not worth discussing

Never in the history of football has anyone ever mentioned arm length in reference to fatigue and injury.

He's on an island on this one. What a waste of time to discuss this.
