Counterpoint: You ARE in position to turn him down, because he already flipped his commitment once, is now transferring from the place he flipped his commitment to, and by taking him, you risk driving out a player that has been committed from the start.
Would love to have his home run ability, but it's not worth potentially pushing someone else out that has already earned their touches.
That might be a different story if Greathouse, Faison, Love, etc. didn't show potential, but those guys are set up for success already imo
