this is what rotoworld says.
Dodgers signed RHP Brandon League to a three-year, $22.5 million contract extension with a vesting option for 2016.
His $7.5 million option for 2016 will vest if he finishes 55 games in 2015. Not only are the Dodgers overpaying League, but general manager Ned Colletti says they're viewing him as their closer over Kenley Jansen. It's surprising given that Jansen has clearly been a better pitcher over the last two and a half seasons, but perhaps they remain concerned about Jansen's heart issue. League converted all six save chances for the Dodgers down the stretch this year while posting a 2.30 ERA and striking out a batter per inning.
this is interesting for fantasy purposes. if Jansen was to close I would think he could be one of the top closers in baseball. if he's not closing to open the season, but could be someone expected to take over if/when League fails.. someone could get a great bargain in Jansen based on where he would be drafted. or one could reach for Jansen expecting him to close, and he never does.
