The NFL is “besides itself” over the Chargers’ choice to exit San Diego in favor of Los Angeles last week, a league source told Adam Schefter of ESPN. “There are a ton of owners very upset that [the Chargers] moved,” said another source, who interestingly added the league hopes Chargers owner Dean Spanos realizes he “bungled” the situation and moves the team back to San Diego. Unsurprisingly, the chances of that happening are rather slim, Schefter notes.

More from LA and several other NFL cities:

• It looks as though the 49ers are “making a huge offer” to reel in Gus Bradley as their defensive coordinator, tweets Drew Copley of CBS47. That jibes with Sporting News’ Alex Marvez report from earlier Friday that there’s “buzz” regarding a Kyle Shanahan-Bradley ticket in San Francisco and runs contrary to the notion that Bradley would’ve only gone to the Niners had they hired Tom Cable as their head coach.
• The Bills announced Friday that wide receiver Sammy Watkins underwent foot surgery for the second time and will be unavailable until training camp. Watkins’ foot was an issue throughout the 2016 campaign, as the three-year veteran sat out eight games and played injured during the other eight en route to a 28-catch, 430-yard, two-touchdown showing. Like Watkins, Bills pass rusher Shaq Lawson also had surgery – on his knee. Lawson’s procedure was minor and won’t keep him from participating in offseason activites. The 2016 first-round pick from Clemson missed six games as a rookie after undergoing shoulder surgery and didn’t make a significant impact during his initial 10 NFL contests (13 tackles, two sacks).
• With $65MM-plus in cap space, the Buccaneers will prioritize re-signing their own soon-to-be free agents before the market opens, general manager Jason Licht revealed Friday (via Rick Stroud of the Tampa Bay Times). “We have a track record of rewarding our players that produce, keeping key players that thrive in the system and we have the salary cap flexibility to make it happen,” said Licht. In light of Licht’s statement, Stroud expects the Bucs to make an effort to retain defensive end William Gholston and Jacquies Smith, wide receiver Russell Shepard and cornerback Josh Robinson.
• Redskins linebacker Ryan Kerrigan had surgery to repair “loose bodies” in his left elbow, he informed John Keim of ESPN.com. Kerrigan, who injured his elbow Dec. 19, will need six to eight weeks to recover. The 28-year-old is coming off his second Pro Bowl season, in which he piled up 11 sacks. Kerrigan hasn’t finished with fewer than 7.5 sacks in any of his six seasons.
• The Chargers will hire Alfredo Roberts as their running backs coach, per Adam Caplan of ESPN (Twitter link). He’ll replace Ollie Wilson, who had been with the Chargers for 14 years. Roberts and new Bolts head coach Anthony Lynn will now work together for a third time – the two were previously on the same staffs in Cleveland and Jacksonville.
