So in thinking about possible scenarios should the Astros trade Roy Oswalt, it's a good time to think about the domino effect that would have on the system.
Scenario: Astros trade Roy Oswalt for two minor-leaguers.
Effect #1: The Astros are down a starting pitcher.
Effect #2: This would lead to a rotation of Wandy, Myers, Norris, Paulino, and XXX. This is assuming that the Astros don't get a starting pitcher who would immediately step into the rotation.
Effect #3: Brian Moehler would likely regain SP5.
Effect #3b: If Moehler doesn't take SP5 for some reason, the Astros could add Wesley Wright or Polin Trinidad from Round Rock, as they are the only starters on the 40-man roster already.
Effect #4: Savings in payroll. Trading Roy, even if the Astros take on half of his contract, would free up approximately $12 million. Given that the Astros will likely have a higher draft pick in 2011 than 2010, $12 million is handy.
Effect #5: It's a visible sign that anything goes on the roster. If Roy goes, Lance could follow, and Myers is more likely to head out. That would lead to a longer list of effects which will be breached later.
What are we missing in this list?
