With the NFL universe on hold, it seems like a decent moment to continue our big-picture look at how each franchise performed during the offseason player-acquisition process. I'm going to go over all 32 teams and rank their work. The rating will be based on how well they addressed needs through free agency and the draft. I'll also give my thoughts on whether or not each team improved or got worse this year. Here we go: Teams that made improvements: Arizona, Baltimore, Buffalo, Cleveland, Dallas, Denver, Indianapolis, Miami, New England, New York Giants, Philadelphia, San Diego, Seattle, Tampa Bay, Tennessee Teams that got worse: Chicago, Cincinnati, Green Bay, Houston, Kansas City Let's start with some good news for Raiders fans. Oakland has come away from its pre-draft visit with Desir Jones saying he'd like to play for the Raiders. They also had a good workout by former first-round pick Jalen Richard. These are signs that general manager Mike Mayock found a way to improve his team through the draft. Last year's draft was considered one of Mayock's best efforts, so this is no small feat. The biggest question mark for the Raiders is at wide receiver.
