This is the one question that has plagued me the most in being un-diagnosed , as it seems to be a general consensus that people with ASD are uncoordinated goofs.
I'm 33, and 99.9% sure I'm on the Autism Spectrum. The traits I have are glaring (without digressing too far from the OP, but, still prefacing--I'll try and keep it short)...I have nearly uncontrollable stereotypies (since as long as I can remember), stemming from being excited or nervous, feel extremely uncomfortable with eye contact, have a couple of obsessive interests, abnormally high rote memory function and reading comprehension, have failed in friendships/relationships with not being able to move past the basics of intimacy etc....
BUT, I was an absolute freak athlete when I was younger--specifically in baseball and basketball. I played on several select teams for both, as well as varsity in high school--the most prolific in baseball, as I could throw one 90+MPH by the time I was 17.
That being said--as good as my hand/eye coordination seems to be, ironically, my fine motor skills are crap (if that makes any sense whatsoever). I have a hard time lacing shoes, or anything that requires intricate, precise motor movements (i.e. cutting things to exact measurements, or working with tools in general).
So, it's very confusing that I seem to be quite disproportionate in my traits/abilities. My best guess is that my genetics are chalked full of so much athletic ability (2 former pro athletes, and 5 collegiate athletes in my family), that even with my apparent ASD, enough managed to manifest itself where I was able to excel
