You are completely missing the point. Your chances of success are higher doing things one way, as opposed to another. I don't know how much simpler I can state it. Most excellent QBs are much bigger than Murray. Therefore, your CHANCES of drafting an excellent QB, are higher, if you go with "prototypical" size. That's why the term exists. Brady is irrelevant. Rd5 is no comparison to what is being discussed. You want Murray in rd3? I'm good with that.
