Injuries continue to derail much of the research we did in the offseason, meaning that we have to dive deep into what makes a great fantasy football roster as we pass the halfway point in the fantasy season.

Rob Gronkowski was taken in the first two rounds of drafts and hasn't returned any of that value yet. While his teammate Sony Michel made us wait a few weeks for production, and once we saw it, it may be taken away again after he suffered a knee injury in Week 7.

Swiss army knife running backs like James White, Phillip Lindsay and Matt Breida have taken a prominent role on our teams despite having largely been after-thoughts in drafts.

The challenge each week is to find the usage, red zone work and consistency and figure out if that work is going to last. This week we look at a handful of players who weren't expected to see much volume before the season and examine if their workload is built to last.
