Trade Evaluation

The following trade just went through in my hoops league: Team A traded Michael Redd and Corey Maggette to Team B for Joe Johnson and Jarrett Jack. Was this a lopsided trade? Should it have been vetoed? Clearly, Team A won out with this deal. Johnson is a significantly better fantasy producer than Redd, while Jack and Maggette cancel each other out. The question is, does the gap between Johnson and Redd warrant a veto? Tough call. I did not vote against the deal, because I'm against regulating trades too closely; however, I can't blame owners who did.
