setup before the throw to receive more in a straight line.... ????? I don't agree with that. Number of factors what the catcher does... Runners on base... does the pitcher need a target.... Just depends. runner on base you set up early and show the mitt as a target the runner signal to hitter where the catcher has set up and the target... No runner on base the catcher sets up early shows the target and base coaches telling the hitter catcher location or the hitter feeling/seeing catcher location... Catcher IMO does shift but has to be ingroove with the pitcher and the ump when to shift. Catcher has to get a feeling on ump... what he likes and don't like. Umps are human (sometimes not sure lol)
