Drafting Strategy - Need vs Best Player Available

[focosteeler]

I wonder if they adjust the bubbles as the draft unfolds? For example, let's say we draft a FS in round 1. Do we take FS out of all the other bubbles? And does our 13th player take his place in the bubble for that round?

I agree too that there's gotta be some BPA at position of need that goes into the picks. But I wonder how that balances out. Let's say for example, I have Ray Rice on my roster. And AP in in the draft and no one's picked him yet. What do the Steelers do? ie. when is a guy too good to pass up even though you don't need him?

I would assume that unless you have a need for 2 future starters at that position you don't draft them back to back rounds 1-4. After that depth comes into consideration for the remaining rounds.
