Not all Scouts and Coaches think alike. However, most do pay attention to tell tale signs.
Once at an event in Texas, we had a kid that was one of the top catching prospects in the country. I saw him entering the park with his parents. Dad was carrying one bag, mom was carrying another bag, and the boy was walking in front of them carrying a soda. This left an impression and quite honestly I couldn't help but wonder what happens when the kid is off on his own.
This kid did end up at a top college, but never realized his potential. Ended up transferring twice and then out of baseball. So the next time I see a mom and dad carrying there son's equipment into the park, I suppose it will bring back memories.
My pet peeve is parents handing drinks, sunflower seeds, etc., to their son in the dugout during a game. Make sure this is done before the game. I hate it when a kid hollers instructions like get me a PowerAde from the dugout during a game. That dugout is off limits to those not associated with the team. However much this bothers me, it doesn't necessarily, by itself, mean a whole lot because it happens a lot even with some top players.
All that said, talent always is the most important thing. You would be surprised what gets over looked when a player has exceptional talent. I bet many years ago there were NBA scouts that hated to see a player with a tattoo. Wonder how good the NBA would be these days if all players with tattoo's were left out.
Bad player - I don't like jewelry
Bad player - I don't like wearing the cap wrong
Bad player - I don't like wearing the uniform wrong
Bad player - I don't like beards
Good player - Those things don't bother me as much because those are things you can change if you want to.
The very best player - He could have hair down to his ankles and still look good.
