IMO it hasn't been neglected (if you're reffering to the preseason games). I think they ran the ball just about as much as they could. Throughout all 4 games, we struggled with running the ball. When your #1 and #2 backs are both averaging about 3 yds per carry (and when Fason starting against the Hawks he avergaed pretty crappy too) its hard to keep establishing your run because you're constantly in 2nd and longs and 3rd and longs.
I'm not sold on the idea that we need a new RB. What we need is a new idea, or a new game plan.
I think the run game is neglected. Offensive lineman love to run block, they love to bring the pain. On one level I think Tice and Co. were so paranoid that the loss of Moss would cripple what they had going for them that they decided to neglect the run game and try to salvage what offense they did have.
On the other hand, I pray it is just a ploy. A lot of good defensive teams have a great run game or a more solid run game then passing game. There is a reason for it. I think it will be a miracle if you can have the high flying finesse offense and a dominant physical defense.
I am of the opinion the lack of run game not only hurts our chances of making a deep playoff run, but it also hurts our defense.
