Do you have a degree?
You can forget about pro sports if you ain't got a degree as a strength and conditioning coach, physiotherapist or sports scientist.
Injuries are part of the game, in every sport that involves contact, athleticism, pace and stress.
It's a pretty ridiculous statement to claim all NBA trainers are incompetent.
First of all, you can't compare College to the pro game. Secondly, Euro League players suffer injuries too.
Thirdly, injuries happen in other major sports too, Football, Soccer etc. basically every sport that involves pace, athleticism, contact and stress.
You wouldn't believe how many Soccer players go down with major knee injuries in Europe.
A lot of NFL players go down with knee, hamstring, quad, ankle injuries too that aren't caused by tackles, but overstressing.
I think you look at it way too simple and too one-dimensional.
These trainers know what they are doing and 99% of them got a degree in eitther strength and conditioning, physiotherapy or sports science.
Of course there are always a couple of guys out there who are not keeping up with time and who use rather ineffecient training methods, but to condem a whole branch is pretty ridiculous.
To follow you logic, athletic trainers in Soccer and maybe even Football must suck too?!
I appreciate your efforts in College and I'm honestly sure that you know a whole lot about training methods etc, but the pro game is a whole nother story.
