I would say that Dez will be a HUGE part of the Cowboy's success this weekend...if there is to be success. If the Dallas running game picks up where it left off in the first meeting (191 yards on 33 rushes) it will force them to commit to stopping the run, thereby forcing some one-on-one match-ups...match-ups Bryant, Beasley, Williams, Witten and Butler must take advantage of, with high catch rates and good RAC. I don't see where GB won't struggle with what to do about the Dallas run game. They definitely won't be able to sit in nickel or dime and get gashed repeatedly (for 5.8 ypc)...something they could afford to do against rush-less New York.
The Dallas o-line and Bryant versus the GBay front seven and secondary. Win those two battles, and you go a long way toward winning the war. Where Beckham failed, Bryant must succeed.
