What Miller showed throughout this past summer proved that he is well worth the approximate $4.5 million he'll make in 2016 via the arbitration process. Teheran, meanwhile, quieted some of his doubters (including me) during this past season's final two months. He too could be a bargain with the $3.3 million salary he will make next year.
There might come a point within the next few years where it makes sense to trade Teheran or Miller. But now is not the time if you truly are committed to constructing a team that will better this year's 67-win total.
