now that he's used to the NL he should do better this year. Sheff may be a good player, but hes not worth as much money as he wants.
Jones will never be anywhere near Sheff in terms of production. It has nothing to do Jones being in the NL for a year. Jones can't hit lefties, period. Look it up.
Jones is a platoon player, Sheff is an offensive monster. It's not even close.
Talking about whether a player is worth the money he wants is moot. IMO, Jones isn't worth 4 million.
