Here's how it works:
some person comes up to you and tells you to do something that's a break in the norm ... and you have a coaching staff ..D1 at that, that get's wind of this "suggestion(s)", don't be surpirsed if they (coaches) ask you this .. "WHAT DID THIS CLOWN LOOK LIKE KID??!!!"
I've had experiences over the years with people like this .. scouts, semi-scouts, so-called scouts, corn dogs(agents), and all kinds of want-a-be's.
You listen to your coach(s), you take the time to develop with their resources, their trainers, their baseball office,... and @#%! these people that are trying to impress you with what they know .. or what they want to see. These so called experts are nothing but trouble to propects like yourself, and athey'll get you ... excuse the word... THINKING.
Pitchers at your level DON'T THINK .. they train, they perform set to a script as set forth by their coaching staff. Besides, if you had the whatforever to need changing ANYTHING your coaching staff at your insitution would have told you so. In fact, when you made that team, one of the reasons for that was due to what these coaches saw .. you in a package, just the way you were. Also, these coaches have a timetable for you .. whether you know it or not, to progres in their program.. NOT SOMEBODY elses.. pro or not.
You've developed a grove for yourself, a style, a pattern that keeps you healthy and injury free (right?), so put your trust and loyalty were it belongs .. in yourself and your coaching staff.
