“use the fatigue and pain factor to gauge how much he should throw”
Try eliminating that pain factor and you will find out there is little fatigue factor.

“the idea that you can tell a 9-year-old's "biological age" “
This is very easy to do, just tale x-rays of both sides shoulder to mid forearm, posterior and anterior once a year on his chronological birthday to determine the Biological age of the athlete. This is very important to know if you want to plan out the best strategy for training progression. For example if you have a 17 year old chronologically and you found out he was a biologically advanced maturer by 2 years you can then decide to train him like an adult, every day. There are hundreds of these types of scenarios to consider that will help in making decisions with youth pitchers.

“some kids are bred to handle more than others”
You have made an argument where none exists; this has nothing to do with durability to withstand the stress of an already known injurious mechanic.
quote:
“made up to excuse overuse of a kid.”
You have this backwards! It was said to put a stop to the over use of all youth pitchers
because of bone deformation that occurs with even non injurious to other body parts type mechanics. They are all susceptible to this growth disturbance.
quote:
“You can't look inside that kid and see what's going on with his growth plates or soft tissue”
Actually this is done every day to determine medical procedure decisions.
You can actually see when the bone at the end of the humerus that does not show up in an x-ray with a biologically aged 9 yo’s then show up as a dime sized white hard spot at biologically aged 10 yo’s then a nickel sized white hard spot at biologically aged 11 yo’s then a quarter sized white hardened spot at biologically aged 12 yo’s then the whole of the Epicondile (the distal end of the Humerus) turns into hardened bone at biological aged 13 yo’s. It is at this point when it is safe to proceed with beginning appropriate training.
Now we can go into the beneficial growth plate info if you wish but I believe there is a better source by studying Dr.Marshalls info.

“Sure, some of us are probably genetically predisposed to be more durable than others,”
Again this is not the argument, all tissues with everybody have the same properties
quote:
” the notion that there is no such thing as fatigue, only bad mechanics, is also bunk.”
No such notion was offered, capacity in humans is very high even when the work to rest interval is short like a couple of seconds but they get a 30 second rest between each pitch making fatigue as debilitating is way off.
This along with pitch counts (in adults) gives the believers in their particular type of centrifugal mechanics an excuse for their inability to continue other than the real culprit mechanics.
quote:
”Someone needs to pull that coach aside and get him set straight before one of his supposed biological wonders gets hurt.”
Right on, traditional centripetal mechanics has hurt 100’s of thousands all ready.
If people are going to keep teaching these destructive mechanics then at least spread the workload to minimize misery.

“More and more these days you see younger kids getting arm surgery”
The increase is only due to the advent of year round baseball!
Club ball youth pitchers decrease their chances of being able to pitch or play in the future at later levels, which is ironically why they are pitching year round. The field players get all the benefits of this extra 8 months of playing. The biggest increase has been in an the lowering of the age in which pitchers produce UCL injuries that were not prevalent in pre 16 byo 20 years ago.
quote:
“because they are standing in the outfield spinning off curveballs without proper training”
What proper training? This only exists under certain conditions and special training!
Any supinated curve crashes your bones together ballistically and all curves thrown outside (forearm outside of elbow thumb up) of vertical are supinated.
There are only 2 pronated curves that I know of and both are thrown inside (forearm inside of elbow thumb down) of vertical and I’ve never seen any traditional pitcher throw one of these.
Which one do you teach, throw or know?

“causing damage to their arms at a young age”
This mechanic destroys all bone at any bodies age even matured hardened bone that after the affliction then builds back deposit and your bone gets larger and larger until you cannot flex or extent your arm well anymore.

“When a child is young, and does start to fatigue, there body reverts back to old, bad habits thus in turn possibly leading to injury”
How can an already injurious mechanic lead you into an injurious mechanic?

“The movement toward pitch counts in youth baseball is a positive one”
Yes, even if they have it wrong! But they do not use the biological age difference calculation to determine correct counts making the studies that produced their recommendation scientifically worthless.
These kids are pitching competitively way too much!
quote:
A 50-pitch appearance spread over five innings is not the same as a 10-pitch inning followed by a 40-pitch inning.
Exactly! The kid who did not have to re-warm up 5 times with inadequate warm up time
(8 pitches) were at lower risk than the kids who warmed up inadequately then threw 10 pitches with more energy and stress from his injurious form of mechanics
quote:
“fatigue and recovery”
Lack of capacity not so much, injurious recovery many mucho’s.
Fatigue (lack of energy) if this is what you mean will give you much less stress with an already injurious mechanic! Fatigue is an excuse that people use to mask the real culprit of injurious accumulation from known injurious mechanics.

”As for long throwing, I'm a proponent”
Are you one of the high parabolic arc practitioners?
quote:
“I disagree with the idea that long throwing doesn't help with location”
The problem is you do not use the same Humeral timing when you long toss as when you use the traditional leg lift pitching motion making this targeting specific for position players but not specific for pitchers.
While long toss gives you some great (but not distance specific) targeting factors in the horizontal adjustment it give you very bad vertical learning! Now add in long distance throwing atmospheric conditions and ball axis presentation air grab where you might do well to have a spotter and a Gilly suit on to perform great parabolic targeting. Not specific by far, NPI.
quote:
“I understand the arguments of the no-long-toss crowd”
Have you considered these the main athletic training tenet ”sport specific “ arguments?
