We sort of stole the thread from the OP. Apologies Curry!
IMO- He's a junior. Short but solid built. Needs work on his blocking technique. A good blocker can block and still have a shot a runner going off the ball in the dirt. If he struggles blocking he has a more difficult road ahead. Fielding percentage can be more misleading that a second baseman. A ball that scoots under a catcher is a wild pitch and on the pitcher but my son, as a catcher, is going to wear that guilt on his shoulders before anyone. Its a passed ball pretty much if it hits his glove and pops out and a runner advances.
Get cleaner video. Non game video. When blocking, focus on that. When receiving...focus on that. Throw downs should have some where its JUST him and his form and then from second showing the throw. Recommend an impartial showcase or something where they take his pop time. Some will use video and then use video itself as the timer to get an accurate measure.
Hope that helps.
