what if Darius plays so well that they can't cut him but after training camp they decide they need another big. Do they cut Scal? Or Pruitt? Or attempt a two for one trade?
Also I think since no one knows the specifics of Walkers contracts how do we know it's guranteed?
Roy can you drop some knowledge on us and explain the rules about sending players overseas but retaining their rights?
I can tell you for sure that they cannot send him overseas after signing him to a contract (or if they did, he would still take up a roster spot).
My guess is they would look for trades first if they need a roster spot. If they were going to bring someone in right after camp, it would likely be through a trade anyways, because there is no one that good out there, other than guys who will be midseason signings like PJ.
If they were looking to sign someone like PJ later in the season, my guess is they will try to trade Davis or Powe either with someone else in a two for one deal, or by themselves to a team with a trade exception, where they get back a draft pick. Considering those guys are relatively redundant, and both of them are Free Agents after the season, one of them will be the most likely to go (assuming Miles sticks around).
