chris davis is just entering his prime as a 28 year old, loads of teams would sign him to 6/80 ASAP. Davis didn't have a real starting role until 2 years ago, when he started to put it all together, and last year was an MVP candidate. Josh Hamilton, a former heroin addict, just got a 5/133 mil contract at the age of 32. Chris Davis would ever sign a 6/80 contract, the idea is insane. Brian Mccann just got 5/85 and his last three seasons combined are less than Davis' WAR last year. The guy was insanely valuable last year. In the second half of the season, as you say, his OPS was .854, exactly the same as Bryce Harper last season. The guy was amazing last season and is def gonna wait for his massive payday. 6/80 is laughed out of the room.
edit: it is similar to saying that ian desmond(whose WAR over the past two seasons is similar to Davis') has a lot to prove and should sign a team friendly deal quick because nobody else in MLB thinks he has proved anything and he will def suck in two years. crappy BB%, average at bets fielder who is a replacement level SS if his power disappears. Desmond's extension would be much higher than 6/80
