There's been some controversy lately regarding the way some non-contending teams have been playing of late.  Specifically, I heard that some (mostly Cubs and their fans) are upset by the fact that the Astro's have changed their rotation and inserted a bunch of rookies with their recent series against the BrewCrew.  The Cubs feel that Houston isn't putting their best team on the field during the most important part of the season.  They think this gives the Brewers a competitive advantage and thus a greater likelihood of winning.  Houston counters with the fact that since they're out of it they want to have a look at some rookies (Oswalt's wife did have a baby so his substituted start shouldn't be argued.)  Knowing their would be some questions, the Astros interim general manager even called the Cubs to let him know of his actions.  Nice gesture, I think.

Question is do you think teams should be allowed to do whatever they want and play any player they so choose or, as a professional courtesy, field their starters/best players most of the time?

Personally, I think teams that aren't in playoff contention should be allowed to play their rookies as much as they wish.  I don't feel this takes anything away from the pennant races.  In fact, I would think the rookies would put forth greater effort to do well as they want to make a place for themselves in the majors.  What do you guys think?
