Oh, I think there's a great deal of question whether Prior would outproduce Miller. As for being crapped on by his employer, I suppose you could apply that argument to any player who gets sent down. So why should Prior be given special treatment? He's not getting it done right now, so he's down for the moment. Why is this bad? If Miller sucks and Prior does well at Iowa, the Miller is out and Prior is back in. Sounds like a solid, merit-based approach to me. Everyone always criticizes the Cubs for being too soft with veteran players. But once they get tougher and demand a level of performance, suddenly everyone's all over them for that, too. I guess they can't win either way. The same reason a rookie with promise should play over a crappy veteran. The chances of Prior improving are better than Miller. All this said I prefer Guzman over both. This is speculation at best. No one knows when, or even if Prior will ever put it together again as it was in the past. If he can't get his fastball back up to at least the low to mid 90s, then he's going to have to really lock in his control to be a more finesse pitcher. Mix into that the fact that when he's on he hits his spots, and when he's off he can't hit the broad side of a barn and it doesn't look like the recovery will be that easy. It's not impossible, but I'd say Miller, at this point, has shown more recovery and a much higher likelyhood of continuing that recovery. Guzman needs a year in long relief IMHO. I'm no MLB pitching coach, but it would be nice to actully let someone adjust to the league while you can still protect them.
