According to Buster Olney, two teams from the NL West have reached out to check on Shelby Miller.

While the Dodgers finished with the second highest fWAR for starting pitchers (24.2), the majority of that value came from Clayton Kershaw (8.6) and Zack Greinke (5.9). After those two, the Dodgers had Brett Anderson (who will be returning on a qualifying offer), Mike Bolsinger, and Alex Wood.
They'll also have Hyun-jin Ryu for 2016 as he returns from a shoulder injury, and Brandon McCarthy once he's fully rehabbed his elbow. Despite all those pitchers, trading for Miller would not only bolster their rotation, but also provide insurance in case Ryu or McCarthy can't rejoin the team as quickly as they hope. There's also the chance that Greinke will leave via free agency, although if the Dodgers are dead-set on keeping him, they shouldn't have any trouble out-bidding any team.
As for the Giants, they desperately need starting pitching help. Behind Madison Bumgarner, they have Jake Peavy, Matt Cain, and Chris Heston. San Francisco's rotation ranked 25th overall in terms of fWAR for starting pitchers (8.9), 57 percent of which came from Bumgarner himself.
With a seemingly set lineup, the Giants main concern this offseason is pitching, and trading for Miller would help accomplish that goal, as well as giving them another reliable starter through the 2018 season. They have a few pitching prospects coming up through their system, but only Clayton Blackburn would appear to have a chance to crack the rotation next season.
For both teams, it's unclear how much of an interest they have in Miller, and what the Braves would want in return. The Dodgers' farm system is much deeper than the Giants', but either one undoubtedly has the pieces to complete a trade if they're serious about acquiring Miller.
