To even out?
Let's see, the Reds quite possibly lost the division in 2006 thanks to the trade and their trade flexibility this offseason took a major blow. Essentially you've got to adjust for what Kearns and Lopez (two guys who currently play at an extremely attractive price) could have fetched otherwise.
So, to offset that I'd say Bray needs to become a quality closer for a few years and Majewski needs to be a quality middle man for a few years (80+ IP, sub-3.50 ERA). That still probably doesn't even it out, unless Bray takes a studly turn, but it at least drags the deal back to being a palatable net loss. Though Bray didn't flash closer potential last year and Majewski suffered an extremely predictable comeuppance. So the more likely target is probably getting some salvage out of the deal - Bray as a competent lefty set up man and Majewski as a league average innings eater.
