Depends on the player and the situation. If AA can get a guy who helps this team this year and next and then results in a pick at the end, it could very well be worth it depending on the price tag of prospects. Perhaps a salary dump of a good player. Or the alternative is AA acquires a longer term option. Im not talking about guys like Price or Shark that will cripple the system. If no such option exists then hold onto the prospects and look to deal in the winter when alternative options may become available. The key is not to rely on hoarding prospects as a viable strategy, nor trading all of them away. A balance needs to be made, otherwise this team will never make a sustained run at contention.
