It's a challenge, Leyland said, because he and Lamont would so often be thinking the same thing on a play. It's also more complicated than going strictly by the scouting reports on opposing outfielders in deciding whether to send a runner home.
"Obviously, we pretty much know how everybody throws. We have scouting reports," Leyland said. "We talk about it. Some guys throw real good but aren't accurate. Other guys don't throw quite as good but are real accurate.
"I think you have to be careful with that kind of stuff, because you don't want to predetermine in your mind, 'Well, if it's hit to this guy, I better not go.' You have to actually see the play, and see it develop. That's why it's such an important job, because sometimes [a ball] is hit to that [tough] guy, but because of the way the ball was hit, he might be backing up to take it, instead of being able to charge it."
Leyland said he also doesn't believe in making decisions at third base according to the score of the game.
"I think you have to let your instincts take over, rather than something in the book," Leyland said. "That's just my personal opinion."
