The 15th spot on the roster is strictly injury insurance. I think you need to leave that slot open for unexpected events. No sense in having to cut someone (and pay them off) to make room. If all else fails, there may be younger, more athletic players on the Toros roster that can be brought up and given a shot. That is what the Toros farm club is for.
So any question about Young or Magette has to be whether they should be in the top 13 players in the rotation, moving a couple of the guys we now have down into the practice squad.
