Allen for Pena was indeed a stupid trade even though I think Pena can be a decent ML reliever -- hell, if David Aaardsma can do it, anyone can.
But let's not overrate the contributions of Allen, Carter or Cunningham thus far. Quentin put up MVP numbers and almost singlehandedly saved 2008 from turning into 2007 nightmare.
And I firmly believe, if not for foot injury, he'd be top 5-10 in MVP voting in 2009, as well.
In other words, I am happy with Q. You can keep Carter.
