I think people are minimizing some of the young guys.
Maliek Collins didn't have much of a training camp, has had to learn and round into shape on the fly and has quickly become a starter and even when Lawrence gets back will likely get a lot of playing time.
Lawrence is still a young, developing talent. Tapper may end up needing a year off, but he has talent. Jaylon Smith was a top tier talent, there obviously is the nerve issue but if it triggers, he will be a nice addition to the defense. Jones is looking like an above average safety. Claiborne is playing at the level of a first rounder. Brown looks good in the nickle.
What we have under contract:
QB - Romo, Prescott
RB - Elliott, Morris, Jackson
FB - K. Smith
TE - Witten, Swaim, Hanna
WR - Bryant, Beasley, Whitehead
OT - Smith, Free, Green
OG - Martin, Collins, Looney
C - Frederick
LS - LaDouceur
K - Bailey
P - Jones
DE - Lawrence, Mayowa, Gregory, Tapper
DT - Crawford, Lawrence, Thornton
LB - Lee, Smith, Wilber, Hitchens, Wilson, Nzeocha,
CB - Carr, Scandrick, Brown,
S - Jones, Heath, Frazier
From PS we have 4-5 guys that very well could be on the roster. WR Jones, WR Mayle, TE Gathers, C Brendel, DE McCain, DE Moore
ERFA - R. Smith, David Irving
FA that we might look to resign - Claiborne, R. Davis, J. Thomas, B. Church, T. McClain, B. Butler, T. Williams
Basically, on offense, biggest need is going to be WR.
The rest we can pretty much focus on D and specifically DE and LB.
