There is seemingly never an off-day for teams in the NFL.

All 32 franchises in the National Football League are currently getting their rosters ready in terms of reducing their salary-cap numbers, making decisions on whether they want to slap the franchise tag on a player, re-signing veterans and letting other plays go.

That means lots of questions for each club. Here, we will limit our inquiries to five. And we’ll do our best to come up with an answer or two.

We are already on Part 4 of our 32-part series. We’ll be going in the current order of the first round of the 2015 draft. After previewing the Tampa Bay Buccaneers, Tennessee Titans and Jacksonville Jaguars, it’s time to look at the Oakland Raiders. The once-proud franchise has not posted a winning record since reaching Super Bowl XXXVII in 2002.
