Padilla at Closer

There's the link to a diary article about a week ago on why Padilla would be a very poor choice as a closer, but here are the summary arguments:

1.  Financially, the Rangers are paying Padilla just over 11 million per year to be a starter.  11 million per year can get you a very good closer, but can only get you a decent #3 / good #4 starter (which is what Padilla usually is).  So you can either try using Padilla at closer and spend 10-12 on a replacement #3/#4, you can hope that one of our current guys to play to that level, or you could use that money to sign a proven closer.  I think the latter is the best choice for the following reasons.  
2.  He has an issue with issuing walks.  His WHIP is currently too high for a closer.  Padilla would be a closer in the style of Cordero...he'd load the bases and hopefully get the last out before someone scores.
3.  He struggles against first hitters faced.  Even last year, which was his breakout year, was bad in this regard.  You can see the stats in my previous diary.
4.  He's bad in high pressure situations.  Once again, see the previous diary for stats.
5.  It's too early to give up on him as a starter.  Last year he proved that he can be a good major league starter.  This year he's struggled (which may be due to elbow problems), so we need to give him a chance to reestablish himself as a starter before making any decisions on changing his role.

Even if we don't wait until the offseason, is it better for the development of the team to have Padilla closing with Wright in his spot in the rotation, with guys like Francisco, Littleton and Wilson not getting a chance (not to mention Benoit and Aki who have proven quite well that they are capable of the job), or is it better to leave him in the rotation and see what we have from the aforementioned others who have the "stuff" to do the job?  I think it's obviously the latter.
