I'm,not a scout, so this is simply an observation and it may have to do with his mechanics during his delivery but I found the angles where he was throwing at the camera interesting. The ball looked very weird coming out when throwing straight on. Maybe because it's totally straight up and down overland, but then watching from the side it looked the same way and once I noticed it I couldn't unnotice it. Also, the ball looked like a balloon in his hands. Prob means nothing, just found it different.
