As good a game as Moreno had yesterday, I think it's at least a bit overstated to say that he's always played well when healthy. True that he was very productive his rookie year and that injuries have held him back, but he has also at times run very tentatively and been prone to fumbling, a couple of the same issues that Ball is now struggling with. Hopefully Moreno can stay healthy and continue to run with the same authority that he's run with ever since returning from his benching last year while Ball makes the adjustment to the NFL.
A lot of those issues are fixed with maturity and experience.
Moreno does have that quick burst to accelerate when he hits the cutback lane. He was running some people over yesterday as well.
Ball needs to learn how to run in the Zone Blocking System and look for the cut back lane. You have to anticipate where the opening will be and that is a skill that can't really be taught.
We will see if he is able to once the game slows down for him a bit.
