This team needs an overhaul.

Make it a 2 or 3 year project.  After those years these are the only players currently on the team that should be remaining.

QB:  Romo

RB:  Choice and Jones

WR:  Austin and Bryant

TE:  Bennett and Phillips

OL:  Free

DL:  Ratliff

LB:  Ware and Spencer

SEC:  Maybe Jenkins

Its looking like we're going to have a high draft pick next year and OL is clearly the most pressing need, however there are no high end lineman.  Next I think we need a shutdown corner.  Newman is good but is aging and hurt a lot.  That's why I would take Peterson or Amukamara.  Then take Solder early 2nd.

By next season we need at the very least a new LG.  Gurode is good enough, Davis is making to much money, and Colombo could stand to be replaced.

In FA I would target an inexpensive Guard and ILB.  Release Kosier and Brooking.  Safety is another huge need, but you can use the draft to fill it.
