Not drafting a QB a mistake?

[CRedskinsRule]

sorry, I should let the close thread movement gain steam, but here is the definition of "mistake" from Merriam Webster:

a wrong action or statement proceeding from faulty judgment, inadequate knowledge, or inattention

So to answer the OP based on this definition:
No, I do not think it was a mistake. Yes I think that SM and others had good judgement, adequate to good knowledge, and were very focused on the task at hand.
