If both are fine in the locker room, and we have no plans for our remianing cap space, or plans for a roster spot they will take up, I say we just keep them both, might as well.
None of us know what's been said back & forth between LJ & his agent and the Cardinals.
My hope is that this was all positioned as "doing business" within the lines of enlightened self-interest (i.e. LJ was allowed to pursue a trade and came up snake eyes), there was nothing personal, the way things played out, he'll be back and there's an opportunity for him to remain a productive part of the Cardinal organization.
The definition of "professional" involves not getting sidetracked by petty outside influences, dealing with the reality of each situation and doing the best job you can under the circumstances.
If LJ and the Cards can come to that understanding, I think LJ Shelton - as a starter at any position along the o-line - or backup swingman can help us.
