Might make more sense to do lists by position first...the varied amount of positions in football will leave a lot more discussion about position importance over time (valuable in its own right) than discussion about the historical merits of a player.
A positional list (top 25? 30? 50? QBs, then RBs, then WRs, etc.) makes for a more seamless transition into an ATD. See: HoH board.
At best, there are six positions in modern hockey: C, LW, RW, LD, RD, G. In football, the number is massive by comparison and therefore drafting an entire team with absolutely zero historical foundation on this board will probably result in wonky, under-researched results or appear to be a project too large to be undertaken start to finish.
I'm in for whatever, as it's a good vehicle to do actual historical research and would provide motivation I wouldn't organically generate...but it's a tough sell in totality...and I say that as an ATD vet myself haha...
