i think a lot of teams wouldn't mind having hall either (not a game breaker, but a better kicker than a lot of teams have), and chad for returns (though he looked much better as a jet with actual BLOCKING in front of him), but i think that post is correct as to who other teams would want to have...
but if we did this kind of breakdown on every team, i'm not sure you'd such much more than 8 guys on them either (out of 22 or so)... so i'm not so sure that its possible to have studs at every position or that its needed to win... where we don't have stars, we have some solid players (being solid is much better than having 2 stars and a bunch of crap.. or in GBs case 0 stars and total crap)... i think you need to judge positions by overall capability and not star power...
any owner would want williams at DC and probably gibbs as well
