That is not the type of injury that typically "goes away" or "heals itself" or that you can truly and permanently cure via rehab---though this last option might work, at least for a time, because Walker is young and athletic. Still, the situation bears watching. If his back turns into a chronic thing, then I can't see any way he would be in Pittsburgh long term. Either way, bringing in a guy like Brignac would be a good idea, as he would at minimum be an upgrade over either Harrison or Mercer.
Neil is still sitting at a 3.3 WAR, which isn't too terribly shabby. His defense is for sucks, but you can live with that if he's hitting.
If his back or his bat fall off of a cliff in the next 2-3 years, he needs to go and we need to move on to the next thing.
