The reason the Skins and Boys are both tanking this year is their owners. Jones and Snyder interfere WAY too much, and both need to hire able GM's to add their football knowledge to the daily operations.
Talking about former Cowboys assistant coaches... Norv is one of those guys who is a GREAT coordinator, mediocre head coach. He does not quite have enough kick em in the ass attitude to be a great head coach. By contrast, Dave Wanstedt is having much more success this year in Miami because he is a bit more of a disciplinarian.
Dallas has problems with both of its lines. The top 3 starters at DT (Spellman, Lett, and Hennings) are gone and the two starting at DT now are both undersized, which is why Dallas gives up so much in the running game. Against the pass, they are more than adequate. The O-line has problems protecting against the blitz (getting better) and with penalties (E Williams). Dallas needs to draft some good lineman first to 1) stop the run and 2) protect Aikman in the pocket because he is not a runner. Then we can draft a good QB next season when we have a high draft pick. This year we are missing our #1 because of Galloway, and wouldn't you know it he is on the disabled list.
Dallas needs to steadily get rid of the older guys and rebuild through the draft. Jerry Jones is a SUCK GM.
