The positive to Raburn is that he qualifies at 2B, LF, CF, RF, OF, and MI, whereas Boesch and Scott are limited to OF. Part of me wants to believe Boesch if for real, but looking at his sub .800 OPS minor league numbers, it's too difficult to see it. Scott is what he is, so if you'd rather have cheap power off the bench, he'd be a good option.
So for me, it's Raburn's flexibility that would prevent me from dropping him.
Hope that helped; good luck!
