Phillies: Which free agent starting pitcher best fits the rebuild?

Lance Lynn is quietly one of the best options on the market this offseason, and has received interest from the Nationals, Orioles, Rangers, and Brewers. Lynn turned down the Cardinals $17.1 million qualifying offer, setting his market price around $18-20 million annually.
Lynn underwent Tommy John surgery in November of 2015, forcing him to miss the entire 2016 season with St. Louis. In 183 career appearances, Lynn has a respectable 3.38 ERA averaging 193 innings and 182 strikeouts over six seasons.
What you see is what you get with Lynn, who won a World Series with St. Louis in 2011, but did not appear in the Divisional Series against Philadelphia.
In most major league rotations, Lynn is a solid number three and a below-average number two. Turning 31-years-old in May, Lynn would be a quality veteran pitching behind Aaron Nola and ahead of Jerad Eickhoff in the three spot.
Should Klentak offer Lynn $85 million over four years it could sway the righty to give Philadelphia a chance.
