There are 5-6 QB contracts I'd rather have. It's not that I think the QB's are better but their contracts are much better to build around. If Dak had signed the same contract as cousins I'd take that as a win. Bigger win if they actually used the savings to pay free agents that can shore up some weaknesses.
You can't say paying cousins/Derek/sam d/fields/flacco plus d Henry, Stephen Gilmore, plus maybe 1 other free agent wouldn't be better than only resigning Dak. Not meant as a slight on Dak, he might be better but only marginally and not for the cost.
