ESPN - Cowboys acquire Williams, agree to contract extension - NFL

Dont yall think the recieve core is good enough anyway? They should have traded for a defensive back, thats the weak spot, Terrance Newman is out, Roy Williams(safety) is out, and now Adam Jones is suspended.
On a side not. The 1-2 recievers are going to be unstopable.
I just don't think this was a smart move.
