Like it or not, Dillion is a 4th string RB right now, his main duties include STs. And his future potential is high, but right now with 2 proven RBs that know what they're doing and coaches trust, vs a rookie with no OTAs, limited training camp, no preseason games... all the rookies are buried on the depth charts.
Except Martin but he's injured, speaking of which UDFA Barnes took Martin's spot and Barnes reportedly (according to one source, in which I want more sources to confirm) Barnes only played 16 snaps, but he was one of the leading tacklers... um, I'm not sure if that's good or bad yet, as they might of been targeting him which made his numbers high, BUT from what I saw, he looked solid, including a GREAT open field tackle from a screen play, which if he missed the ball carrier had open space and blockers.
Also the Vikings DL was weaker, but they never really seemed to give the Packers too much trouble, even with two injuries, line reshuffling and a rookie playing. I think someone from PFF mentioned, how they didn't think people were giving enough credit to Jenkins who was expected to play LG this season, then went to RT and had no troubles, then mid game, had to switch back to LG, and no troubles, switching position at ease. Also Runyan stepping in and looking fairly good.
Though again, Vikings are trying to rebuild their CBs and retool their DL, so everyone thought they might have EA down year, except the cocky head coach whom gladly points out has never had a bad defensive year, some Minneapolis reporters seem to be kinda happy that their reasonable questions about the defense might be a concern, instead of the head coach, our defense will always be good, I'm in charge head coach line, as they didn't seem to appreciate the dismissal of the (IMO reasonable concern) questions.
