You are basing your assessments solely on numbers. You copied and pasted biomechanics assessments other actual scouts with knowledge have made. You aren't watching him pitch. You don't see his side sessions. You don't know what he may or may not be working on. As mentioned, when you make mechanical adjustments, you aren't better day 1. The reality is most often you become worse off the get go when you make mechanical changes whether it be golf, tennis, baseball..etc. How has he progressed with these changes? His last two outings have been better....was he lucky, or is he getting better? You have no f***ing clue, because you haven't seen him pitch....thus the conjecture attached to your opinions. Your opinions do not have all the required knowledge to come to the conclusions you are.
What's my opinions on the guy? I have none, because I haven't watched him pitch. I can have a soft opinions on the guy based on the information that is available. Sure the walks and command issues are disconcerting, but is it enough for me to write off a 21 year old kid with his velocity and movement....absolutely not.
