I see the cowboys cutting Biggs and signing a FA to replace him. His contract is not guaranteed and it's expensive, so cutting him and replacing him with Mankins (depending on FA rules) or Nicks would be a huge upgrade at a small cost. As the BTB article revealed, Biggs is the exact wrong type of OL for Garrett. No reason to wait another year when there are several FA options out there. I am hopeful a 2 year deal gets it done with Kosier (well, I'm really hopeful they move on and sign two guards that are under 30, but that is probably too costly).
I legitimately think the Cowboys sign at least 1 new FA on the o-line and 1-2 on defense. Huff and Nick/Mankins would round out this team nicely.
Connected to this, MB3 and Biggs are gone. TNew re-negotiates his contract. RW11 is here to stay, and anyone who says otherwise doesn't know what they are talking about.
