You make a great point.
If we were talking about NEXT YEAR (or for that matter, any year), there's no question my answer would be Halladay.
I'm not trying to compare Tim Wakefield, Clay Buchholz, Brad Penny and John Smoltz (the 2009 version) to Halladay either (some geniuses on Boston Sports Radio actually asked what the Sox would do with Halladay

).
But if the Sox are going to use their young chips to get better THIS YEAR, they definitely need a bat!
