You don't think they tried to trade RJ and Marvin? $8M and $11M are not tradeable contracts, especially for their production. How many teams that are trying to make the playoffs had cap space to take on those two? Now had they been making close to the vet minimum, there would have been a market for them.
We do not know if they did or not. Expiring contracts are attractive to teams going into this free agency class. But who knows...
