I've always leaned towards more aggressive running with more information. There's nothing more important as far as predicting what will likely occur if you know the times for the runner, P, and C. Given current SB ratios, I can't imagine any intelligent manager wanting a player's SB ratio more than the times of the runner, P, and C. Accumulative stats go in the toilet compared to play by play data, I'm glad the stat world is catching up to that idea. On top of knowing the times of the runner, P, and C, it's also important to know the judgement of the players involved. As a general rule, giving somebody like Soriano or Juan Pierre the green light to steal pretty much whenever they feel like it is a horrible idea. On the other hand, I had no problem with Maddux getting the green light. He steals once a year if and only if he has a perfect read. I guess what I'm saying is that for anyone short of the absolute most intelligent players in the game, SB are a valuable tool only if executed well, and the situations well evaluated.
