I can understand your anger and frustration but I think you might be "throwing out the baby with the bath water".
I agree that this team has grown beyond MacPhail's ability to improve it. Let's give him credit where it's due. He convinced Angelos that "yes men" were not going to get the job done and that a much bigger investment was necessary in the farm system to build a winning team. He has traded for Jones, Hardy, Reynolds, and Tillman. IMO, his inability (or unwillingness) to be aggressive about making trades has caused him to miss opportunities and his obsession with squeezing the last nickel out of deals has cost us quality players (Miguel Sano - 2009, George Sherrill - 2010, etc.).
Also, IMO, Joe Jordan has done a good job with the budget he has been given to work with. 2008 was the first draft under MacPhail and the team went after "over slots" in the middle and late rounds that their budget had precluded before. Look at the 2008 draft:

Ryan O'Shea 27 Reliever
That's 20 players that have MLB potential and it's a fair guess that we're looking at at least two impact players and four regulars from that group. The 2009 and 2010 drafts have similar outlooks. If Jordan was given a bigger budget there might be more in the pipeline.
Part of the problem is that it normally takes about five years for the full impact of a draft to be felt at the major league level. We've seen everything we're going to get from the 2007 and earlier drafts so it will be 2013 before we can expect any real impact from ALL of the 2008 and beyond classes. That's not Jordan's fault.
The issue of why our prospects don't develop to the level of their potential can be blamed on MacPhail. He has done little to improve the quality of instruction in the minor league system and almost nothing to improve conditioning and nutrition on a system wide basis despite clear signs that it was a problem area. Look at Matt Albers. When he played for us I called him "Fat" Albers. I felt that if he got into shape he would be an effective pitcher. Did anyone see him pitch for the Sux the other day? He's lost about thirty pounds and three runs from his ERA.
While I agree that MacPhail is part of the problem and needs to go I see Jordan as part of the solution. Let's hope the next GM will tell Angelos what needs to be done and gets a budget that will allow him to do it.
