The Las Vegas Raiders are in the first year of the Pete Carroll and John Spytek era, so there is still a bit of experimenting to do. The roster had tons of turnover this offseason, and unlike past regimes, this tandem is trying to build a long-term winner instead of patching up the team every offseason.
This means that an abundance of younger players are in the building, and there are only a handful of high-dollar veterans like Maxx Crosby or Geno Smith. The rest are simply cheap additions or reclamation projects that the team is not tied to on a long-term deal.
