West's value to other teams will decline because of his age faster than his ability. Getting some pieces for him now makes sense rather than wait until later. West and Hibbert are so slow in the front court that without Lance and Paul it is going to be much more obvious.
If things continue to go the way they are going it is unlikely that West or Hibbert will be pacers in 2 years anyway. PG will be out a year and his first year back he will be getting back into playing shape but not yet the player we know now.
If we stand pat then IMO our season goes the way Hill goes.
