We heard last week that the Raiders and star linebacker Khalil Mack are not close on an extension, and Mack has not yet reported to the team’s offseason workout program. GM Reggie McKenzie, though, remains confident that a new deal will get done, and there does not seem to be any reason to believe otherwise at this point. Scott Bair of NBCSports.com takes a crack at the value of Mack’s next contract, and he suggests that a six-year, $120MM pact (with around $65MM in guarantees) could be in play. He also says the team is unconcerned about Mack’s absence at this point, though the Raiders do want to get a deal in place before training camp.

Now let’s round up a few notes from west division clubs, starting with more out of Oakland:

• Jared Cook has been mentioned as a potential cap casualty this offseason given that he is owed a $5MM salary and can be cut without any dead money remaining on the books. But Bair does not believe the Raiders will part ways with Cook, though that could change if the team selects a tight end in the early rounds of this month’s draft.
• The Chargers‘ run defense was the weakest part of an otherwise strong unit in 2017, and with only Denzel Perryman locked in as a starter at linebacker for 2018, Dan Woike of the Los Angeles Times believes the Bolts could make a play for an LB early on in the draft. If the team does not trade up to select a talent like Tremaine Edmunds or Roquan Smith, Rashaan Evans and Leighton Vander Esch should be available when the Chargers are on the clock with the No. 17 overall pick. As Woike notes, the team also needs to decide what it wants to do with Perryman on a long-term basis, as the Miami product is entering the last year of his rookie deal.
• In a separate piece, Woike suggests that the Chargers could look to bolster their run defense by selecting a defensive lineman in the early rounds of the draft, with Vita Vea and Da’Ron Payne being tied to the team in various mocks. Los Angeles has stayed out of the free agent market for linebackers and defensive lineman thus far, and Woike notes that Jay Bromley could be a name to watch if the team cannot fill its DL needs in the draft.
• One team that decidedly does not need to draft a defensive lineman is the Rams, although Gary Klein of the Los Angeles Times said the team could still be on the lookout for DL depth in the later rounds of the draft. Klein notes in a separate piece that the Rams — who will not be on the clock until the third round — do need to address their LB corps. The team has three fourth-round selections and four sixth-round picks, and Klein says Los Angeles will be on the lookout for LBs, especially edge rushers.
