First lets make a few things clear for the uninitiated 
1. A Big Board is not a mock draft so it does not take positional value or needs into account, therefore it is not necessarily a projection of who will go where in the draft. Its simply ranking the prospects (by tier) regardless of position or any other peripheral considerations. So, for example, I know the top two QB's will most likely be drafted with or above some of the TIER 1 prospects, but that IMO is partly due to positional value, so that doesn't mean I will have them in TIER 1 which is reserved only for the elite prospects in my view.
2. Some people rank their Big Boards in precise order, 1 thru 50 or what have you, but I prefer to use Gil Brandt's method of breaking it down by tiers. Frankly I don't feel like we outsiders have enough information to rank players in precise order. I feel a little more equipped to break it down by tiers in no particular order.
Tier 1 = Elite Blue Chippers
Tier 2 = Borderline Tier 1 BC's
Tier 3 = Middle 1st RD Value
Tier 4 = Late 1's and Early 2's
Tier 5 = Middle 2 Value
Tier 6 = Late 2's and Early 3's
Tier 7 = 3rd RD Value
