Dane is about 180#. Ray is the same weight. Hartline is the same weight just taller (although he really bounces around out there). Dane may be taking a lesson from Hartline and in doing so, he got dinged up. These guys throw themselves around, block for others, get hit catching passes and sometimes need to deal with a linebacker that may have a good fifty pounds on them. He could use a few pounds but IMO the weight gain might slow him down. However, strength training would benefit them. WRs are like gazelles, they run fast and are elusive, but they are fragile. It goes with the territory.
TG II is a good example. One celebration in the endzone, a foot gets steps on voila. He's out of commission.

That sucks for Dane! Wish him a speedy recovery.
From a medical sense, I disagree that weight has nothing to do with a concussion.
From Wiki
It is the transfer of a conserved quantity called momentum. Higher velocity and higher weight translates to higher momentum which in turn results in greater acceleration/deceleration forces.

No, because then when he hits something with his mass being bigger he would suffer less decelleration...

Good point. But it seems like the reduced decelleration is offset by the increased momentum. I'm sure I'm just not getting it and I certainly understand why being bigger would cause you to impact the other player more, but fundamentally getting bigger simply adds to the impact if everything else remains a constant. Yes, you are delivering a bigger blow, but you and the foreign object are still receiving the force of the impact.

Then try the "science of common sense". If two guys of the same size hit each other head on, they both stop at the same point, but if one guy is significantly bigger, they both don't stop at the point (the smaller guy gets pushed back and the bigger guy continues to move forward).
Bottom line is that if Scoot were, say, 20 pounds heavier, the impact he'd receive from a 230-pound tackler wouldn't affect his 200-pound body like it would when he has a 180-pound body.

Exactly, I can speak from experience. I was a 225 lb offensive tackle my sophmore year, and suffered 3 mild concussions. Over that year I hit the weights hard, bulked up, and never again had an issue with concussions. There's a major difference in force. Since F=Mass x acceleration, A big bulk up of say twenty pounds can greatly increase your force and therefore help to balance out net forces. Acceleration on the other hand is harder to increase in such a great number. Sorry for dorking up the forum, I have a degree in sports studies so I'm all over the science of sport.

Oh, that would be bad. Hey... if he started or stopped reading too quickly, would he get a concussion? *ponders*DaddyBigBucks;936689; said:
Anyway... I hope Dane is feeling better very quickly... already fun to watch him doin' his thing on the field, and I think we're all looking forward to more. :)

I'll second that. Under the circumstances, it is ironic that Ray will be filling in for Dane tomorrow. The tables are turned. I suppose Dane will have to work his way back into the lineup again just as Ray did. It would have been nice seeing all the WRs out there on Saturday having a scoring frenzy!
Dane may miss the 500th homegame, but I look forward to 501 thru 524.

Momentum example
Let an engineer weigh in on this. :) Sorry, I couldn't help but comment. This only explains the principle of momentum and not the conservation of momentum law. It gives you an idea of some of the mechanics involved.
Momentum = mass x velocity. Here's an example, even a smaller WR can have more momentum than a lineman because he has more velocity (even if lighter). The problem is when the linebacker or lineman is faster or as fast as the WR. Then the impact is a greater train wreck. Or when the WR hits two defenders, their combined mass (assuming the same velocity) means a greater combined momentum. Then there's the change in momentum which is why the players wear helmets and we have airbags in cars. When the two masses collide, we need something to absorb the impact. As smithlabs said yada, yada, yada. Lets watch some football.
A wide receiver (m = 60 kg), a tight end (m = 90 kg), and a lineman (m = 120 kg) are running down the football field.
Velocity of WR = 9 m/s ; Momentum of WR: 60 x 9 = 540 kg m/s
Velocity of TE = 6 m/s ; Momentum of TE: 90 x 6 = 540 kg m/s
Velocity of Lineman = 3 m/s ; Momentum of Lineman = 120 x 3 = 360 kg m/s
Compare the velocities of these three players. How many times greater is the velocity of the wide receiver and the velocity of the tight end than the velocity of the lineman?
Which player has the greatest momentum?
A. The tight end travels twice the distance of the lineman in the same amount of time. Thus, the tight end is twice as fast (vtight end = 6 m/s). The wide receiver travels three times the distance of the lineman in the same amount of time. Thus, the wide receiver is three times as fast (vwide receiver = 9 m/s).
B. Both the wide receiver and the tight end have the greatest momentum. They each have the same amount of momentum - 540 kg*m/s. The lineman only has 360 kg*m/s.
