Last week's epic start to free agency thrust all 32 NFL teams into makeover mode.
The most striking series of transformations came in the backfield, where a rash of clubs were quick to remake their stable of runners.
Here's what else we learned over the weekend:
As aerial attacks continue to explode, teams are in trouble if they can't lace the field with five -- even six -- cover men on any given down. This month's open-market bum-rush for secondary help is the upshot.
- Tampa's trash is Cincy's rediscovered treasure. After the Bucs parted ways with Michael Johnson -- their heavily hyped free-agent signing from a year ago -- the Bengalsswooped in on Sunday to sign their former pass rusher. Adding Johnson, in theory, helps a defense that finished dead last in the league in 2014 with a paltry 20 sacks. Johnson has a shot to start at end, but with just 7.5 takedowns over the past two seasons, he's produced his share of bad tape since leaving Cincy.
- The Browns were silent during the first week of free agency, but NFL Media Insider Ian Rapoport reported Sunday that Cleveland is determined to sign veteran wideout Dwayne Bowe. Browns general manager Ray Farmer knows Bowe from their time together with the Chiefs, but our excitement is tempered. The ninth-year pass-catcher can move the sticks, but adding a past-his-prime Bowe to a group that includes Brian Hartline and Andrew Hawkins is hardly the stuff of dreams. The Browns loom as a contender to lead the AFC in carries next season.
- Raiders general manager Reggie McKenzie desperately needs pass-rushing help, but he emphasized over the weekend that free-agent Greg Hardywon't be brought to Oakland. Tangible off-the-field concerns aside, someone is going to grab Hardy -- one of the league's finest quarterback-chasers -- at a bargain.
- We're keeping an eye on the quarterback situation in Buffalo, where the Bills are serious about giving Tyrod Taylor a chance to start. "No one is really ahead of the other guy right now," Taylor said, hinting that coach Rex Ryan lured him to town with the promise of a battle under center. Why not? Matt Cassel is a middling veteran and young EJ Manuel has been a major disappointment. Even if he doesn't win the job, Taylor is sure to see meaningful sub-package snaps in Roman's offense. Take a look at Colin Kaepernick's pre-starter tape from 2012 for clues on how Taylor might be unleashed.
- Free-agent signings and a flurry of trades have cost a handful of veterans their jobs. Case in point: Greg Jennings, who was cut by the Vikings after Minnesota swung a deal with the Dolphins for Mike Wallace. Jennings is done as a big-league playmaker, but he won't have problems finding work. Sticking with a team beyond August will be the challenge.
