Simple google search for images of players throwing makes it obvious, as does reviewing film of games at whatever level you choose. I just watched OK vs TX and seam orientation was random. It's really pretty obvious that players aren't doing this. I find it quite comical that anyone here thinks they are.Just out of curiosity do you have some showing they aren’t..that’s fair right?
Note also that it's on the one making an extraordinary claim to provide the evidence.
