According to Billy, Yost has pretty much given everybody the green light to steal. Kaegel says Yost believes that Billy can steal ten bases this year.
That is just plain nuts. There is the argument that every now and then you should intentionally call a low-percentage just to keep the other team on their toes, to let them know "Hey, these guys might try anything." That makes sense to me, as long as you do it every now and then rather than all the time.
If Yost wants to run more, though, Billy's really not the guy to do it more than three times a year. If Yost wants to send Avilés or Escobar or Alex more than he did last year, that would make some sense, since those guys have some speed and athletic ability and do not weigh 250 lbs.
