Philly has alot of guys in arbitration, so while they may have alot of money to spend, it dries up quickly.
Nola, Velasquez, Neris, Franco, Morgan, Altherr, Cesar Hernandez are just a few who hit arb, so that will cost a decent chunk of money.
Even in the slim, slim chance they landed Machado and Harper, i doubt both go there with better market/clubs like NYY, LAD, CHC to name a few going after both. Their biggest concern is defense, Hoskins cannot keep playing in the outfield, gives up too many runs. Phillies defense is their biggest concern, for someone who is huge into analytics like Kapler is, it's amazing he doesnt value a huge analytic like defense.
