With the Brewers needing a first baseman and the first-base market at this point being incredibly thin, this is a possible match.
The Mets are trying to trade Davis after a disappointing 2013 season. One could argue 2012 was disappointing too, though he recovered from a disastrous start to have a huge second half. That is all Davis could really hang his hat on after a good rookie year, as his 2011 season was marred by injury.
In 2012, Davis hit .255/.346/.542 with a whopping 20 home runs after the All-Star break in only 251 at-bats. This led many to believe he was in for a breakout season last year as a 26-year-old in 2013. Instead, Davis hit just .205/.326/.334 with nine homers in 377 big-league plate appearances in a season that required a demotion to Triple-A.
There's certainly enough talent to salvage and maybe a change of scenery helps, but giving up much value for Davis would be a gamble.
