Offensive line first, running back second. At least for the first 3 or 4 yards in most cases. Asking a running back to get positive yards without adequate blocking isn't really fair. Sure, some of the greatest running backs of all time could do it more often than the less skilled. Yet every back, from terrible to average to great, has success with good O-Line play. Denver did it in their SB years. Cinci did it last year. I think an upgrade to the offensive line yields better results than an upgrade at running back. I think if we can get one more solid guard, and one more solid tackle prospect, then the Pack will be in a much better situation with their running game. It is after the first 3-4 yards that really separates the great backs from the rest. The great ones have the skill and/or ability to make the one guy miss, run his *** over, or cut it back to an open area most backs didn't even see. I think LT is a perfect example. The offensive line play in terms of run blocking was gradually deteriorating in San Diego over the past 2-3 years. Almost everyone, sports fan and analyst alike said that LT was done or he should hang it up. The Jets who have one of the better if not one of the best run blocking offensive lines in the NFL pick LT up, and he is making plays again. Even in San Diego when he wasn't doing that great he was still a threat to go all the way, especially as a reciever. In New York, he is a full blown monster again.
