1)people who know baseball alot better than me say pop times are important
2)game times/performance are the ultimate proof
but, that said, pop measurements are most easily/often taken in ideal conditions, and if you're not sub 2 sec. in ideal conditions - well, you're sure not gonna get faster in a game setting. And if a player is working on the skills to get faster it's a pretty valuable yardstick for his progress.
often the other teams running game strategy is determined/affected by the catcher's pregame throws (no batter in the box there)
if he's quick ya may have little chance to see an "in game time" that day
it he's slow you'll probably see "in game times" ALL DAY LONG
also a good agressive catcher will sometimes be right on the edge flirting with CI (interference) because he takes the SB personally -
tho he'd not want to "take away a strike" from his pitcher, they'd both HATE just letting guys get into scoring position -
go for it Kremer, you're on the right track
regarding scouts/college coaches - don't worry they know what they're looking for & no-one's fooling them
