The decision comes down to numbers. ith our run focused offense, it's unlikely we carry more than 5 WRs. Bruce, Jones, Morgan and Hill are locks. That leaves Battle, Ziegler and a rookie (assuming we draft a WR) to fight for the 5th spot and a spot on the practice squad. Morgan and Hill might not be better than Battle at the moment, but both have an upside that secure their roster spots.
If there were no rookie involved and we were choosing between Battle and Ziegler for the 5th spot, I think you go with Battle because of his special teams ability-- better to have a guy who can contribute than one who just rides the bench. Plus, Ziegler is more likely to accept a practice squad role.
Assuming there is a rookie WR chosen and he does show the ability to contribute (even if just on special teams initially), he's got to be given that 5th spot. In that case, I expect Battle would be moving on, because I can't see him accepting a practice squad role. Ziegler on the other hand ends up on the practice squad in either scenario, an injury away from a roster spot.
