No SF fan would be complaining about the trade if the team had made the playoffs last year. It didn't work out, oh well. It's not like Wheeler was blowing anyone's minds in the minors. He was our top pitching prospect only because MadBum had arrived on the major league level. Same people criticized giving up our top prospect a few years back for Freddy Sanchez, and look where Tim Aldersen is now.
Wheeler is regarded as a top 10 pitching prospect in all of baseball. Ypu got 2 months of Beltran, and the Giants didn't make the playoffs. It was a very bad trade for SF.
