I’m not sure I like the idea so much given it’s success when tried back in 2003. If you mean go with the hot hand, the person who's had the most recent success, then we probably would have seen Seanez come in the 8th last night, and not Hansen. Either that or Paps get used over and over until he’s cooked by September. A lot to ask from a young arm.
It all goes back to the problem of how inconsistent the relievers have been, basically since the beginning of the season. A bullpen by committee might work if the people in the pen weren’t so up-and-down all the time, but you can’t always judge them on a game by game basis. One day they look unhittable and the next game they suck.
