Personally I don't think Doom has the same impact Seymour was having at the time. 80% of his production could be had at 1/3 of his original cost (doom). These are not that similar of cases. In reality this is simply a thought that tied back into this thread.
A Fantasy GM Draft where the Broncos had the chance to trade for Jared Allen. Med made the case that it is not good to give up this much for an aging Allen. I disagree Allen would be the prototypical player I would want our our DE. This is not going to be a dynasty we are trying to squeeze a Lombardi out of the end of the Manning Era.
