Does Pacheco take over next year?
I wouldn't operate under that assumption, given the amount of churn in the NFL.
If it isn't someone bonafide like Jacobs coming in to take the job, it will be some more-talented rookie like Bijan, Gibbs, Tucker, etc.
It's not often that a 7th round sophomore is handed a starting job on a plate.
Not totally unheard of (i.e. Arian Foster), but he'd have to be impressing the staff in a major way. A smattering of touches here and there doesn't indicate that level of internal excitement, but rather the typical backup/JAG/journeyman trajectory you expect from those ultra low draft capital pickups.
