Spiller is killing it right now, but there's still an opportunity for Jackson to make this a true RBBC situation if he's fully healthy. It might be awhile before we see him healthy, but there's obviously a chance that Spiller could go down with an injury and then if Jackson is back, he could be a stud again.
Spiller is a great big-play back and when he's hitting like this it doesn't matter, but he still needs to improve as an all-around back in terms of pass protection and running with power inside, etc.
It would take a pretty good quality FA for me to consider dumping Fred. It's a long year and he could still pay off around the fantasy postseason.
See, some Spiller fans get angry when I say this. But I think it's more than an opportunity, I think it's likely. Look, I love watching Spiller play. I think he's a singular talent. But sometimes fans get caught up with one guy, when in fact, two guys make the team more dangerous. And I think it's completely reasonable to conclude that given how good this offensive line is blocking, a 50/50 split will make for very high RB2 numbers for both players.
