If you're moving on from Bogey, I figure you better be improving in the two weaknesses (defense and rebounding) he has in the context of our team in order to make up for the downgrade in offensive value.
Swapping for Clarkson would make more sense, as several people have mentioned, since we're not really needing an upgrade in rebounding in a Clarkson replacement.
But this is all moot as Boston's unlikely to be interested in either.
