They have a lot of fringey depth, the same dudes that didn't stop them from winning 100 games and the World Series last year. I remember the Philles bashed one of them right back to the minors last year.
Even with a $300 million payroll you can't keep adding $20 million guys 6 or 7 starters deep This is why the Phillies did the Luzardo deal, especially because they are still paying Walker.
Of course, they may also still get Sasaki.
