You're making it seem like there is a HUGE difference with D1 players and everyone else. There isn't as much as you're making it out to be. Every weekend in high end travel ball, there are multiple great teams at the big tournaments with mixtures of D1, D2, D3 , NAIA, and probably some JUCO players in there, and many times you would never know the difference. I see D3 players taking D1 pitchers yard, and stealing off of D1 catchers. Granted there are many D1 players who really have no business playing D1, but there's not as big of a difference that you are making it out to be. P4 obviously usually stand out a bit more, but many of these players look pretty similar. The biggest difference with all of the levels is with pitching. you can see it in the WCWS right now. Pitching is everything.
