I've been following this thread for a while now and wish to add some commentary in support of what PG is saying. Yeah, all these things matter, but when you're evaluating positions, you look at different things. For a pitcher, you measure his velocity of his fastball, as well as secondary pitches. You also look at command, ability to change speeds, pitchability. You might note his time to home from the stretch, but that is only a supplemental note, if mentioned at all. For an infielder, you're going to note how he fields, moves to his left and right. How he throws, can he make the throw from the hole or behind 2nd, that kind of stuff. NOBODY is going to measure or care how he tags runners. It is way down on the list of things to worry about, compared to the other aspects of playing either position.
For a catcher, its a bit different. Throwing out runners is one of his primary responsibilities. Therefore, pop time is an essential measurement of a catcher's ability.
If you're selecting a pitcher based on his time to home, you don't know what you're supposed to be evaluating. In the big picture, that doesn't amount to a pimple on Boog Powell's butt!
