NO team, certainly not even the Pats, have good solid talent at all positions.
And NO ONE has really good depth at all positions. Its not like it was in the early 90's; it will probably never be that way again. You do the best you can with what you draft, find or can buy. Right now the Cowboys have pretty solid people at just about every position, and some good backups.
RT - we have some people that are OK- Vollers, Noll maybe. The Rookie has size and strength- we will see if he can do it. That is the last real need position.
Our FS pick up will do ok- if not Davis probably will be ok. Either one will almost CERTAINLY be an upgrade over last year. And THAT is what is important.
