Berry, who was diagnosed with Hodgkin's Lymphoma last December, amazingly got back to the practice field last week. Prior to that diagnosis, this guy was one of the most dynamic safeties in the game, exhibiting exceptional cover skills, awareness and playmaking ability as a deep-middle player, as well as the grit and physicality needed to be an enforcer between the hashes. If he returns to form after shaking off the rust in training camp, Berry will help a unit that allowed just 6.4 yards per attempt in 2014 become even stingier this season. Peters was arguably the top cover corner in college football prior to a season-ending suspension that abruptly closed his career at Washington. He is a long, pesky defender with exceptional cover skills and a versatile game. He can shadow receivers utilizing bump-and-run, bail or off techniques, which is rare for a young player. If Peters can remain focused on the details, he eventually will team with Sean Smith to give the Chiefs a dynamic cornerback tandem on the edges. (Remember: Smith is suspended for the first three games of the season.)
