I have not posted much since signing up to post on this site, but I do read as many posts as possible. You have become one of my favorite posters since you joined the site.
Your comments are almost exactly what a couple of scouts told me about Robert during the AFL season.
I personally watched Robert play in 15 AFL games this past Fall and spoke to some scouts about him after games. In the AFL, he struck out only 13 times in 79 PA’s so there was no evidence of the “swing and miss” comment made by another poster. I know this is a small sample size and he did strike out at a much higher rate during the minor league season. However, the fact that he was battling through thumb injuries during the minor league season and his hand was still stiff for a fairly long time after the cast was removed, scouts told me his stiff hand hampered his swing & bat speed, in which he was beaten by fast balls and it also sapped his power. Apparently, the stiffness in his hand was finally gone when playing in the AFL as, like you said, he impressed everyone that I spoke with during the AFL. One scout said that he still needs to improve in recognizing off-speed pitches and some work on his swing so he is not yet a finished product offensively. But, as you said, he is still very young and I think the sky is the limit for this kid.
I agree with you that he may have more raw talent than anyone in the our system. What I saw this Fall was a kid that can hit, hit for power (a blast of a HR in Mesa & another to CF at Camelback), tremendous speed on the bases and great range in the outfield and a very strong arm. In one game, he made a strong and perfect throw from fairly deep RF on one hop to the catcher that should have easily nailed the runner at home, but the catcher somehow missed the tag.
